Homework Statement
Convert a3'a1 + a3'a2 + a3'a0 + a3a2'a1'a0'
to an expression (well, it's a circuit eventually) that would only employ NAND and NOR gates. Use DeMorgan's Law.
Homework Equations
a'+b'=(ab)'
The Attempt at a Solution
I applied DeMorgan's as the problem suggested...
(a3'a1)''+(a3'a2)''+(a3'a0)'' + (a3a2'a1'a0')''
Which yielded:
( (a3'a1)' (a3'a2)' (a3'a0)' (a3a2'a1'a0')')'
This is in just NAND and NOR gates, but the circuit isn't really aesthetically appealing... Is there a simplifying trick I'm missing? Or is this just what it is supposed to be?
Thanks in advance!
