Please read the whole question first, then send a
solution if you are able to solve it!
A synchronous sequential circuit is to be designed having a
single input X and a single output Y to detect single change of
level (from 0 to 1 or from 1 to 0) in a 3 bit word a
produce an output Y=1, otherwise Y=0. When a new 3-bit word is
to come, the circuit must be at its initial (reset) state and there
should be a time delay of one clock cycle between the words. Draw
the state diagram, draw the reduced state diagram, state
transmission and output table
