Digital logic is at the core of all digital computers, and yet it is entirely based on three fundamental operations, designated AND, OR, and NOT. See how it's possible in these pages…..
These pages now include coverage of the major logic families as well as some practical experiments that you can perform with real components to see for yourself how they work.

• DC Electronic Theory.
• AC Electronic Theory.
• Op Amps and Analog Circuits.
• Take a look at optics.
• What's inside these semiconductors?

Line Clock - Play-Hookey

"In many digital circuits, we need a regular and continuous train of pulses to control the timing of various circuits. In some cases, we want two separate pulse trains, one the inverse of the other. In other cases, we may want two square wave pulse trains in quadrature...."
