1. (6 marks) Let PQ and RS be two 2-bit binary numbers. That is, each of P, Q, R, and S is 0 or 1. Design a circuit that has four inputs, P, Q, R, and S, and one output Z such that the output is 1 if and only if P RS 2 410. Your answer st include (a) an Input/Output table, (b) a Boolean expression, and (c) a drawing of the circuit corresponding to your Boolean expression. Important: Generate the truth table for your Boolean expression at http://web.stanford.edu/class/cs103/tools/truth-table-tool/ and attach a printout to your assignment. Without this, parts (b) and (c) may be assigned zero marks
