# Race around condition in JK flip flop

Race around condition in JK flip-flop: J&K equals to the output changes or complements its output from 1->0 and 0->1. This is called toggling output or uncontrolled changing or racing condition. Consider above J&K circuit diagram as long as clock is high and J&K=11 then two upper and lower AND gates are only triggered by the complementary. Prerequisite - Flip-flop types and their Conversion Race Around Condition In JK Flip-flop - For J-K flip-flop, if J=K=1, and if clk=1 for a long period of time, then Q output will toggle as long as CLK is high, which makes the output of the flip-flop unstable or uncertain. This problem is called race around condition in J-K flip-flop. This problem (Race Around Condition) can be avoided by. Race around condition: For JK flip-flop if J, K, and Clock are equal to 1 the state of flip-flop keeps on toggling which leads to uncertainty in determining the output of the flip-flop. This problem is called Race around the condition. This can be eliminated by using the following methods Race around condition is the most important condition in Digital electronics. In J-K Flip flop, when J=K=1 the output changes its state. When a clock pulse width tp is applied the output will change from 1 to 0 after a time interval of Δt, where Δt is the propagation delay through two NAND Gates in series The circuits you added at the end of your question do not show two edge-triggered flip-flops. Those circuits show two level-sensitive latches. The symbol in the top schematic shows a little triangle at the clock pin of each flip-flop. That triangle is the standard indication that the device is edge sensitive Let us begin with the basic concept. JK latches were basically constructed to neutralize the limitation of SR latches. We cannot give a input of S=R=1 in SR latches as the output can't be predicted whatsoever (analysis of the circuit will provide.

### Explain the race around condition in JK flip-flop

• ated by using master slave latches (JK) or flip flops which are edge triggered devices
• Race Around Condition In JK Flip-flop. For J-K flip-flop, if J=K=1, and if clk=1 for a long period of time, then Q output will toggle as long as CLK is high, which makes the output of the flip-flop unstable or uncertain. This problem is called race around condition in J-K flip-flop
• For the racing around to take place, it is necessary to have the enable input high along with J=K=1. As the enable input remains high for a long time in a JK latch, the problem of multiple toggling arises. But in edge triggered JK flip flop, the positive clock pulse is present only for a very short time. Hence by the time the changed outputs.
• ing the output of the flip-flop. This problem is called Race around the condition. ' This condition also exists in T flip-flop since T flip-flop also has toggling options

Race-around condition in flip-flops. Race Around Condition In JK Flip-flop - For J-K flip-flop, if J=K=1, and if clk=1 for a long period of time, then Q output will toggle as long as CLK is high, which makes the output of the flip-flop unstable or uncertain Race around condition of JK Flip Flop. For high inputs of J K flip flop, only the lower NAND gates are triggered by the outputs that are compliment to each other i.e Q and Q'. So while high inputs are connected to flip - flop, at any instant, one gate is enabled and other gate will be disabled Avoid racing condition in JK Flip flop: If the clock On or high time is less than the propagation delay of the flip flop then racing can be avoided. This is done by using edge triggering rather than level triggering. If the flip flop is made to toggle over one clock period then racing can be avoided Since this 4-NAND version of the J-K flip-flop is subject to the racing problem, the Master-Slave JK Flip Flop was developed to provide a more stable circuit with the same function. The Master-Slave JK Flip Flop has two gated SR flip flops used as latches in a way that suppresses the racing or race around behavior 16. Consider the following statements 1. Race-around condition occurs in a JK flip-flop when the inputs are 1, 1. 2. A flip-flop is used to store one bit of information. 3. A transparent latch consists of D-type flip-flops. 4. Master-slave configuration is used in a flip-flop to store 2-bits of information

At the same time, the slave is enabled, and the current value of master output is transferred to the output of the flip-flop (slave output). It solves up the problem occur in JK Flip Flop and solves up race around condition which occurs in other flip flops.

T Flip Flop: In JK flip flop when the two inputs are shorted the resulting flip flop is called T Flip Flop. If T=1, it acts as a toggle switch

Race Around Condition in JK Flip-Flop - When the J and K both are set to 1, the input remains high for a longer duration of time, then the output keeps on toggling. Toggle means switching in the output instantly i.e. Q = 0, Q' = 1 will immediately change to Q = 1 and Q' = 0 and this continuation keeps on changing Master-Slave JK-Flip Flop. When edge-triggered flip flops were not invented in the past, then Master-Slave JK-flip flop were used to remove the problem of the race around condition in JK flip flop. Construction: A master-slave JK flip flop is constructed using two components: master and the slave. The master component consists of clocked JK. Race condition occur in RS flip-flop. When the S and R inputs of an SR flip flop is at logical 1 and then the input is changed to any other condition, then the output becomes unpredictable and this is called the race around condition. RS flip flop:-An SR Flip Flop is an arrangement of logic gates that maintains a stable output even after the. For JK flip-flop if J, K, and Clock are equal to 1 the state of flip-flop keeps on toggling which leads to uncertainty in determining the output of the flip-flop. This problem is called Race around the condition. This can be eliminated by using the following methods. Increasing the delay of flip-flop; Use of edge-triggered flip-flop

### Master-Slave JK Flip Flop - GeeksforGeek

A Flip Flop is a memory element that is capable of storing one bit of information. It is also called as Bistable Multivibrator since it has two stable states either 0 or 1. There are following 4 basic types of flip flops-. SR Flip Flop. JK Flip Flop. D Flip Flop. T Flip Flop race around condition in flip flops In JK flip flop whne the value of J and K =1 and at the same time vlaue of clock is 1 ,so according to the truth table of J=k=1 the value of output should be toggled so the value keep on changing till the change in the clock pulse.which is not acceptable .This problem can be removed by making it master slave.or making ff as edge triggered The JK Flip Flop is a gated SR flip-flop having the addition of a clock input circuitry. The invalid or illegal output condition occurs when both of the inputs are set to 1 and are prevented by the addition of a clock input circuit. So, the JK flip-flop has four possible input combinations, i.e., 1, 0, no change and toggle JK Flip Flop-. JK flip flop is a refined & improved version of SR Flip Flop. that has been introduced to solve the problem of indeterminate state. that occurs in SR flip flop when both the inputs are 1. In JK flip flop, Input J behaves like input S of SR flip flop which was meant to set the flip flop. Input K behaves like input R of SR flip.

### How To Avoid Race Around Condition in JK Flip Flo

Race Around Condition: Race around condition occurs only in JK-Flip-Flop when J = K = 1. and the propagation delay of the flip-flop is less than that of clock propagation delay. Therefore the output is changed several times in a single clock pulse Race around condition happens when current output triggers a change in future output (as in the case of JK flip flop). Within the same clock pulse the output keeps changing. (resulting in race between 0 & 1) Toggling is when a particular input changes the output (i.e. from 0 to 1 or vice vers ### Won't this jk flip flop circuit be facing a race condition

### How can we overcome race around condition in JK Flip Flop

1. Race around the condition in JK flip flop occurs when J = 1 and K = 1 but the output keeps toggling between 0 and 1 instead of changing only once while clock is 1. The time interval of oscillation is the delay of the circuit. Thus to prevent this toggling Master Slave bistable JK Flip Flop is used
2. The advantage of a JK flip-flop is that it removes the not allowed condition present in the SR flip-flop for an input of SR=11. In JK flip-flop, an input of 11, gives a toggle output.

The difficulty of both the inputs to be '1' in case of S-R of the invalid state is eliminated by a J-K flip-flop by using feedback connections from output to the input.

* The counter designed has 4 JK-Flip Flops. The JK-Flip Flop triggers at every negative going edge of the clock signal. * A latch is a level-sensitive device. The major problem with latch-sensitive devices is that during the same level of the clock signal, a race around condition might occur thereby making the device prone to glitches. This is. For JK flip-flop if J, K, and Clock are equal to 1 the state of flip-flop keeps on toggling which leads to uncertainty in determining the output of the flip-flop. This problem is called Race around the condition. This can be eliminated by using the following methods. -Increasing the delay of flip-flop-Use of edge-triggered flip-flop-Use of. RACE AROUND CONDITION. In logic circuits, Race condition means The situation at which the two inputs of a logic circuit change at the same time and that will make the output tentative. The inputs are in competition to change the output. It generally happens in the devices which have the output as the feed-back input of the circuit

### J - K & Masterslave Flipflop

The JK flip flop is basically a gated SR flip-flop with the addition of a clock input circuitry that prevents the illegal or invalid output condition that can occur when both inputs and R are equal to logic level 1. Due to this additional clocked input, a JK flip-flop has four possible input combinations, logic 1, logic 0, no change and. then to avoid race-around condition occurring with j-k flip-flop. (a) t p = t = T (b) t p - t = T (c) t p < t = T (d) t p < t = T. Asynchronous counter shown in figure below is (a) MOD-21 counter for avoiding race around condition pulse width should be smaller than the delay and this should be smaller than the time period of the pulse. (c

1. Flip-flop J-K dalam IC 7473 Flip-flop JK yang terdapat di dalam IC 7473 disebut Negative-Edge-Triggered Master/Slave J-K Flip-Flop (datasheet lain menyebutnya Positive Pulse-Triggered, yang pada dasarnya hampir sama maknanya). Dalam satu IC 7473 terdapat dua Flip-Flop J-K dengan konfigurasi kaki-kaki sebagai berikut. Gambar 7. Diagram koneksi.
2. Construct T - Flip flop (fig 6.5) and repeat step 2 and 3. Inference: Different types of Flip flops (RS, Clocked RS, JK, D, T) are Constructed using IC 7476 and hence their truth tables are verified. Viva Questions: Difference between latch and flip-flop. List the applications of flip-flops. Explain the operation of JK master slave flip-flop
3. The T (toggle) flip flop is a complementing flip-flop and can be obtained from a JK flip­ flop when inputs J and K are tied together. When T = 0 ( J = K = 0), a clock edge does not change the output. When T = 1 (J = K = 1 ) a clock edge complements the Output. The complementing flip-flop is useful for designing bi­nary counter
4. In this mode, the flip-flop has an enable pin. The enable pin when set to 0 disables the flip-flop hence the output Q and Q' remain 0 irrespective with the inputs applied. When the enable pin turns 1 then output starts getting value with respect to the input applied. Connect the enable to a timer or a clock and we get a clocked SR Flip Flop
