COCO F09 SOLUTION HW #08 3/5 For X,Y selectors: 0, Z, Z, Z Now solve the problem with selector inputs X, Z instead of X, Y. For X,Z selectors: 0, Y, 0, 1 , 0 D0 Y D1 0 D2 MUX F 1 D3 S1 S0 X Z 4. (5 points) Implement the following functions using a PAL. On the schematic diagram on page 4, draw circles to indicate unblown f uses. Please do it neatly: if you make mistakes, print another copy of the PAL instead of crossing out marks (or use the computer to make the marks and then print it out).
