ECE 102 - Homework 9

Due 11/02/2017


  1. Consider a 3-bit counter which counts the sequence 000,101,011,111,110,100  and repeats the sequence.
    a) Use T flip-flops to do the design.
    b) What will happen if the counter starts in state 010?

  2. Design a 4-bit counter which counts the sequence 0110,1010,0011,1111,0100,1001,0101,1110,1000
    and repeats the sequence:
    a) Use D flip-flops

    b) Use T flip-flops
    c) Use S-R flip-flops
    d) Use J-K flip-flops

  3.  Draw the state diagram corresponding to the following
       sequential circuit.  Show all the steps in your analysis.
