(Regular Logic Implementation Methods) You are to implement a combinational multiplier. It has two 2-bit inputs and a 4-bit output. The first 2-bit input is represented by the variables A, B; the second 2-bit input is represented by C, D. The outputs are W,X,Y,Z, from the most-significant bit to the least.

(a) Complete a truth table that describes the functional behavior of the multiplier.


(b) Find the minimum sum of products forms for the outputs using the K-map method.


(c) Implement the multiplier using the P16H8 PAL of Figure 4.42. How many of these PALs do you need?
