Problem 1. (30 Points, 10 Points for each part) Switch Representation of Digital Circuits: Draw the CMOS circuit diagrams using NMOS and PMOS transistors for the following functions. Assume that you have both the uncomplemented and complemented values of each primary input (A, A, B, B, C, C, D, D') directly available as inputs, if needed. (1) F = (A+B) C+D (2) F = A(BC+D) (3) F A'B'C'
