Use a PLA diagram having only an AND plane and an OR plane. 7. Implement a BCD to Gray code converter using a 4 × 16 × 4 PAL. Each PAL output collects 4 different product terms. 8. Use a 4 × 12 × 4 PLA to implement a comparator circuit. The circuit takes two 2-bit binary numbers as inputs, denoted by AB and CD , and computes the four functions AB = CD ( EQ ), AB ≠ CD ( NE ), AB < CD ( LT ), and AB > CD ( GT ). Use a PLA diagram having only an AND plane and an OR plane. 9. Show the connections of the section of a 16L8 PAL required to implement the functions: 1 D C A D C B A Z D C B D C AB D B A ABCD Y + + = + + + = 10. Repeat Pb. 9 on the functions: D C B A ABCD D C B A CD B A Z D ABC BCD A D C B A D C B A CD B A Y + + + = + + + + = 2...
