[IMSAI Guy] grabbed an obsolete XOR gate and tried a classic circuit to turn it into a frequency doubler. Of course, being an old part, it won’t work at very high frequencies, but the circuit is super ...

Including XOR gates in your functions offers significant benefits by reducing transistor and track counts and increasing testability. As designers, we're used to representing digital functions using ...

In the 8th May 2006 issue of EE Times, I published a “Brain Boggler” in my Logically Speaking column. The idea is that we have a black box with three inputs called A, B, and C; and three outputs ...
