Window comparator using op amps

A window comparator using operational amplifiers lets you know if a signal (voltage level) is within or outside a previously defined acceptable voltage limit. Using a comparator or operational amplifier that controls the upper voltage level and another comparator that controls the lower voltage level, a window comparator can be implemented.

Push – Pull Amplifier

A Push – Pull amplifier is called that way, because it uses 2 groups of transistors and only one works at a time. One group pushes in one direction while the other pulls in another direction. Each group is responsible for amplifying a single phase of the input wave.
