1) a) (5 points) Design the simplest sum-of-products circuit that implements the function: f(x1,x2,x3)=m(2,5,6,7) b) (3 points) Draw the logic network and compute the cost. (Hint: the cost in term of number of transistors, defined as follows : NOT : 2, OR \& AND (2+2 *number of inputs , for example 2 input OR gate =2+22=6,3 input OR gate = 2+23=8)
