For this problem, you are to design a simple combinational logic circuit The circuit is a 2- bit priority encoder with inputs I2 and I1 and outputs Z1 and Z0. The circuit behaves as follows: • If I2I1 = 00, then Z1Z0 = 00 (no active input) • If I2I1 = 01, then Z1Z0 = 01 (low-priority input, X1, is active) • If I2I1 = 1-, then Z1Z0 = 10 (high-priority input, X2, is active) Note that...

One way to specify a combinational circuit is to describe its function by a truth table, in which we list all possible input combinations and their desired output values. Assume that the circuit has n inputs. (a) What is the size (number of the rows) of the table? (b) What is the problem with this approach?
