Brown and Vranesic, Problem 8.9  A sequential circuit has two inputs w 1 and w 2 , and an output, z . Its function is to compare the input sequences on the two inputs. If w 1 = w 2 during any four consecutive clock cycles, the circuit produces z = 1; otherwise, z = 0. For example w 1 : 0110111000110 w 2 : 1110101000111 z : 0000100001110 Derive a suitable circuit....
