Show how to realize the following functions:
X = ABD + A'C + B'D' + C'D'
Y = A'C + AD + C'D'
Z = CD + A'C + AB'D
using
a) PAL14L4 (14 inputs, 4 outputs, AND-NOR structure, each NOR has 4 AND gate inputs)
b) PAL12H6 (12 inputs, 6 outputs, AND-OR structure, two output OR's have 4 AND gate inputs and four output OR's have 2 AND gate inputs).
NOTE: you need to show only appropriate product terms used for PAL implementation and explain whether these functions can be implemented using each PAL. (you do not need to show the PAL diagram)
