Question
Let's analyze the following synchronous sequential circuit:
First step is to derive the equations for output/s and flip-flop inputs.
The circuit uses a D flip-flop, and because a D flip-flop has only one input, we derive one equation for the excitation D of this flip-flop.
• If there were more D flip-flops, we would need to derive one excitation equation for each, e.g. DO, D1, D2. etc.
• If the flip-flop was a JK, for example, we need to derive two excitation equations for each JK flip-flop, one for J and one for K. So if there were several
JK flip-flops, we would have something like J0, KO, J1, K1, etc.
In the circuit, notice how D is connected to a 2x1 mux with select signal S. Complete the expression for D below:
D = SQ' +
