I find that if I’m trying to make a point with a student or a colleague about a circuit, sometimes the Falstad online simulator is worth a few thousand words. You can draw the circuit, play with the ...

Since 1972, scientists have known there are four basic circuit components, but if you've spent any time in an electrical engineering classroom, you probably only have experience with three: capacitor, ...

Fig 1. A typical CMOS input circuit comprises a “P” and “N” transistor. One is fully “on” for logic high, and the other is “on” for a logic low. Fig 2. When a CMOS input pin is at logic high or low ...

VHDL and Verilog are hardware description languages, used to describe and define logic circuits. They’re typically used to design ASICs and to program FPGAs, essentially using software to define ...

Computers use electrical circuits which have two states – on or off. This can also be represented as 1 or 0 or True and False. Logic gates take an input of True or False and give an output of True or ...
