(c) Design the 8-input NAND gate using only two-input NAND gates and two-input NOR gates.
(d) Compare the number of gate inputs in parts (a), (b), and (c). 2 Solution:
H (a) (b) (c) As can be seen, (c) requires the fewest gate inputs (14 pins), followed by (a) (15 pins), then (b) (20 pins).
6. Verify using Boolean algebra that the circuit shown below generates the exclusive-NOR function. X B
C Y Solution:
Deﬁne the internal NOR gate outputs as A, B , and C as shown in the ﬁgure. It...
