Circuit design "lab" exercise (25 points total): circuit to implement a "three-of-four" function. circuit takes four digital inputs (A, B, C, and D) and produces a single outputs Create a circuit should be would be 1 when at least three inputs are high, and O if fewer than three are high. may use as many AND, OR, and NOT gates as you like, but you may only use pes of gates for this exercise 2) Complete the four-variable truth table for the three-of-four" function. (Remember, this function should be a 1 if three or four inputs are high, an otherwise.) (5 points) three or four inputs are high, and a 0 C D 1 1 1 1 1 1 1 0 0 0 1 1 1 1 0 1 1 0 0 1 1 1 0 1 0 1 0 1
