For the circuit shown below,

Take the initial value of Q3Q2Q1Q0- binary equivalent of the last digit of your student ID.

Q3 is MSB and Qo is LSB

(1) Plot Qo, Q₁, Q2, Q3 and P for L-0 and Enable=1. Consider the propagation delay in

flip flop

(2) Plot Qo, Q₁, Q2, Q3 and P for L-1 and Enable-1. Consider the propagation delay in

flip flop

(3) Identify the counting sequence for above two cases
