Push – Pull Amplifier – Push – Pull Amplifier Operation

Marcel — Sun, 22 Mar 2020 23:06:55 +0000

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.

Properties of the Alternating Current (AC)

Marcel — Wed, 11 Dec 2019 15:52:00 +0000

What is Alternating Current?

The difference between an alternating current and a continuous current is that the continuous current flows only on one direction. The alternating current circulates first in one direction and then on the opposite one, repeating this process continuously.
