7) Develop a "majority" circuit with four single-rail inputs, A, B, C, D, and one output. It works such that if three or more inputs are 1, the output is 1. Otherwise, (all inputs are 0 or one input is 1 or two inputs are 1), the output is 0 Majority Combinational Circuit f(A, B, C, D) First, obtain the truth table of the function. Second, implement the function by using a single 74LS151 chip. No other gate or chip can be used
