Combinational Circuits | Definition, Types & Examples

A combinational logic circuit has four inputs (A, B, C, and D) and one output Z. The output is 1 if and only if the input has three consecutive 0's or three consecutive 1's.For example, if A=1, B=0, C=0, and D=0, then Z = 1, but if A=0, B=1, C=0, and D=0, then Z=0. Design the circuit using one four-input OR gate and four three-input AND gates.
