IMSAI Guy] grabbed an obsolete XOR gate and tried a classic circuit to turn it into a frequency doubler. Of course, being an ...

I'll now describe one of the multiplier's circuits at the transistor level, in particular an XNOR gate. It's interesting to look at XNOR because XNOR (like XOR) is a tricky gate to implement and ...

A typical digital circuit can be designed using basic elements like Transistors, Logic Gates, Flip-Flops or even using complex elements like microcontrollers, microprocessors and other computing chips ...

Don’t be thrown by its simplicity though. [Andrew] quickly moves on to talk about switching transistors and how they are used to build gates like the OR NOR gate seen above. If this is the ...
