1. (a) Given an 8-bit unsigned binary number s2 = CE16 + 568, find S2. If s₂ is in two's complement representation, what is its equivalent decimal value? (6 Marks) (b) Given a logic function y(a,b,c,d) = Σm(0,1,2,9,15)+x(4,11), where x(4,11) are the don't-care terms, find the minimised sum-of-products (SOP) expression. (9 Marks) (c) Given a logic function z(a, b, c, d) = a (b+c d), draw its CMOS circuit with minimum number of transistors. If the currents of the CMOS circuit are as in Table 1, find its fanout.
