Below is a circuit, implemented using a 3:8
decoder, for a strange counter. Derive the state diagram for the
counter. Begin by assuming the circuit starts in the state where
all flip-flops are 0. The order is ABC, for example, state 001
corresponds to A=0, B=0, C=1.

Complete the truth-table below.

What is the next state from 000? _____100______

What is the next state from 010?
_____001______

Are there any unused states? If so, what are
they? _____110______

Complete the state diagram below.
