Solved: A sequential circuit has two inputs and two
Chapter 14, Problem 14.25(choose chapter or problem)
A sequential circuit has two inputs and two outputs. The inputs ( \(X_1\) and \(X_2\) ) represent a 2-bit binary number, N. If the present value of N plus the previous value of N is greater than 2, then the \(Z_1\) is 1. If the present value of N times the previous value of N is greater than 2, then \(Z_2\) is 1. Otherwise, \(Z_1\) and \(Z_2\) are 0. When the first pair of inputs is received, use 0 as the previous value of N.
(a) Find a Mealy state table or graph for the circuit (minimum number of states is four).
(b) Find a Moore state table for the circuit (minimum number of states is 10, but any correct answer with 16 or fewer states is acceptable).
