What is race around condition?
The "Race Around Condition" occurs when J+K=1 i.e. When the FF is in the toggle mode.the race around condition in JK latch can be avoided by:a) Using the edge triggered JK flip flop.b) Using the master slave JK flip flop.
What is the main difference between normal JK flip flop and master slave JK flip flop?
A normal JK flip-flop has the output change state based on the input on the leading edge of clock, while the master-slave variety predetermines the output on the leading edge of clock and then effects the actual change of the trailing edge of clock, making it impervious to race conditions.
What are cause of glitches that some times occur in ripple counter?
Glitches in ripple counters primarily arise from asynchronous signal changes, where the output of one flip-flop changes before the next flip-flop has stabilized. This can result in temporary incorrect states as the propagation delay between flip-flops leads to race conditions. Additionally, variations in power supply and signal integrity can exacerbate these glitches, causing unexpected behavior in the counter's output. Proper design techniques, such as synchronous counting or using debouncing methods, can mitigate these issues.
What are the disadvantages of JK flip flops?
JK flip-flops have a few disadvantages, including the potential for race conditions, which can occur if the inputs change too quickly relative to the clock signal, leading to unpredictable output. They also require careful timing management to avoid glitches, as both inputs can change simultaneously. Additionally, JK flip-flops can be more complex to implement and understand compared to simpler flip-flop types, such as D flip-flops, making them less ideal for basic applications.
Why does the master slave J-K flip flop not requires an edge trigger while the J-K flip flop does?
The master slave has two flip flops, a master stage and a slave stage. The master stage is committed on one transition of the clock, while the slave stage is committed, based on the master stage's state, on the next transition of the clock. This eliminates race conditions, unless the clock pulse is so narrow as to make them become an issue again.The non master slave, however, bases its output state on the JK inputs just prior to one clock edge. In this respect, its somewhat no different than the master slave variant, except that the output in the master slave is committed prior to actually changing state, whereas the output in the non master slave is committed very close to its actually changing state. The problem is simply one of design - if the input is a function of output, then race conditions in the non master slave can make the output indeterminate, and that is poor design. No ifs, ands, ors, buts, or maybes. :-)>

How can master slave flip flop prevent race around condition?
RACE AROUND CONDITION OCCURS WHWN BOTH THE INPUT ARE HIGHAND THE OUTPUT THUS UNDERGOES A TRANSITION STATE.FOR EXAMPLE CONSIDER THE INPUT VALUES IN A JK FLIP FLOP;ie;J=K=1 ,THE OUTPUT Q0=0 IN NORMAL CASE WILL CHANGE TO 1 AND VICE VERSA. THE REMEDY FOR RACE AROUND PROBLEM CAN BE ELIMINATED BY USING A MASTER SLAVE J-K FLIP FLOP'S
How do you overcome race around condition?
by using master slave flip flop

How master flip flop is used to overcome time race in jk flip flop explain?
In a master-slave flip-flip arrangement, the master flip-flop determines its state on one clock edge, while the slave flip-flop determines its state on the following clock edge. This way, the end-to-end output does not ever change on any one clock edge, so no race condition is possible.
What is race problem?
Race-around condition is arises in level triggered JK flip flop . when you apply 1 to both j and k input than the flip flop will toggle on every clock or it may toggle multiple times in the same clock pulse . it may be possible that new output will feedback to input before clock goes to zero (for positive edge triggered) if it happens than the flip flop will toggle on time again . this undesired toggling is called Race-around condition. overcome by - using edge triggered flip flop. using very narrow clock width.

Jk master slave flip flop?
consists of two r-s flip-flops wherein clock of the first is negated and applied to the second.it is used to avoid the problem of race-around condition by making sure that the first flip-flop is triggered during the positive going edge and the second during the negative edge of the clock pulse.
What is race condition in flip-flops?
A race condition occurs when the output of a logic circuit is fed back into the input in such a way as to change the output, such that settling of the inputs delays the final stabilization of the outputs. It can also occur when two inputs to a circuit change at the same relative time, but the result depends on time sequence, such as in a D-FlipFlop where the clock is edge triggered.. In a full adder, for instance, propogation of carries can delay the final output, resulting in performance (speed) degradation. That is why many full adders have look-ahead carry logic. In essence, to avoid a race condition, you want to design the circuit so that propagation delay does not accumulate in series. A striking example in my memory was where an 8085 microprocessor system used WR/ to drive the databus drivers, while at the same time using WR/ to strobe the destination latches. That was a race condition, and it made the final contents of the latches indeterminant.
What are the disadvantages of flip flops?
The primary disadvantages of flip flop is their reacting time between the input signal and resultant Output if the signal changes between this reaction time the flip flop is unable to identify....... another disadvantage is that their is a Race between the flip flops when connected togather to change their stages
