Sequential-Circuits

Question 24

We want to design a synchronous counter that counts the sequence 0-1-0-2-0-3 and then repeats. The minimum number of J-K flip-flops required to implement this counter is __________.

A
4
B
5
C
6
D
7
Question 24 Explanation: 
Given sequence is 0-1-0-2-0-3
There are 3 transitions from 0.
Hence ⌈log23⌉ = 2 bits have to be added to the existing 2 bits to represent 4 unique states.
