The functional difference between SR flip-flop and JK flip-flop is that

1. JK Flip-flop is faster than SR flip-flop
2. JK flip-flop has a feedback path
3. JK fkip-flop accepts both inputs 1
4. none of them

c)JK flip-flop accepts both inputs 1,1 which is not accepted by SR (giving invalid output)

option c is correct. but in JK we have the feedback as well. so i guess both the options b & c are correct. correct me if i m wrong

The main difference between a JK flip-flop and an SR flip-flop is that in the JK flip-flop, both inputs can be HIGH. When both the J and K inputs are HIGH, the Q output is toggled, which means that the output alternates between HIGH and LOW. Thereby the invalid condition which occurs in the SR flipflop is eliminated.

Hence,Option(C)JK flip-flop accept both input 1.

SR  have feedback or not ?

0
Well, isn't it obvious? If there is no feedback, then it is not a flip flop
0
i mean to say only C is correct answer.

@yankur9  No SR flip flop are asynchronous, so it is technically a latch only!
All flip flops are edge triggered and synchronous(triggered by clock pulse), just check out the diagram of SR flip flop from anywhere...
So out of SR and JK only JK is a true edge triggered flip flop!

Hope this helps

buddy i was simply reply for @cse7

i know . whatever u are telling. :)

JK FF is SR FF + 2 latches, so definitely not faster than SR FF. Option A eliminated

Option B is incorrect, because every FF has that. It's not a "functional difference".

Option C is correct. It accepts 11 and toggles on it.
