Question

4) Analyze the circuit shown below by finding tits transition table 3 to 8 Decoder Y7 Y6 wa Y5 D Q Y4 Y2 Wo Y1 Q0 Clock. ansitun table

Answer 1

We first start by making the truth table for the Decoder (3x8). For this question, we need to keep in mind the connections. Here Q1 is connected with W2 and Q0 is connected with W1. Also W0 is the input A. So while solving the equations we substitute W2 W1 and W0.

Next we find the next state equations for the flip flops. For the D flip flop it is the input itself. For JK, it is the equation I've written which can be easily derived from it's truth table.

Using the next state equations the transition table is made.
