Question

Design a two bit counter circuit that counts from 0 to 3. It should have states 00, 01, 10 and 11. The initial state of the counter may be assumed to be 00. The counter will be in following successive states: 00, 01, 10, 11, 00, 01, 10, 11, 00, 01, 10, 11, 00 ... Use any flip flop to design the circuit. You must design counterusing state transition diagram and Karnaugh's map

Answer 1

which program language?

Answer 2

A sequential circuit is deifned by the time sequence of the following :

External inputs

External outputs  

Internal flip-flop binary states.  

The first figure defines a state table and state diagram which best describes the  behaviour of the circuit.

 

There are two flip-flop inputs for counter i.e. A, B. The next state of flip-flop is given in the table. DA showcases flip flop inputt corresponding flip-flop-A. This counter requires 2-flip-flops.
