perplexus.info :: Logic : Triple Negative

Triple Negative (Posted on 2004-02-12)

Using only two inverters and an unlimited number of AND and OR gates in a logic circuit, show how to invert an arbitrary number of inputs.

(For instance, if you have four inputs, the circuit will have four outputs that are the inverses of the four inputs)
