Question

Transcribed Image Text:A UV flip-flop behaves as follows:
• If UV = 00, the next state of the flip-flop is the complement of the present
state.
• If UV = 01, the next state of the flip-flop is 1.
• If UV = 10, the next state of the flip-flop is 0.
• If UV = 11, the next state of the flip-flop is the same as the present state.
A Moore sequential circuit has one input X and one output Z. The circuit outputs
Z = 1 if and only if the number of 1's received as inputs is a multiple of 3. Derive
a state table for this circuit and realize the state table with UV flip-flops. Label
your states S, and make the encoding the binary representation of i. For example,
S₂ should correspond to Q1Q2 = 10.
