Question:
In Example 9.21 we designed a circuit that replicates every second pulse on input w as a pulse on output z. Design a similar circuit that replicates every third pulse.
Example 9.21
Problem: A circuit has an input w and an output z. A sequence of pulses is applied on input w. The output has to replicate every second pulse, as illustrated in Figure 9.79. Design a suitable circuit.
Compare this with the FSM defined in Example 9.4 in Figure 9.13, which specifies a serial parity generator. The only difference is in the output signal. In our case, z = 1 only in state B. Therefore, the next-state expressions are the same as in Example 9.4. The output expression is
