A logic function f(a, b, c, d) = 1 when abcd = 0000, 0001, 0010, 0011, 0111, or 1111. otherwise it evalues to 0

a) write boolean expression for this function

b) reduce the express using boolean properties

c) implement the inverse of this function using CMOS circuit. name each NFET as N1, N2, ... etc, and each PFET as P1, P2...

d) which NFET's participate in driving the output to a 0 when an input 0011 is applied to the circuit

e) which PFET's participate in driving the output to a 1 when an input 1000 is applied to the circuit
