Power Amplifier Definition, Properties and Classifications

Power amplifers

A Power amplifier is an electronic device which¬†provides sufficient power to an output load to drive a speaker or other power device, typically a few watts to tens of watts. The main purpose of this amplifier is to raise the power level of the input signal, to get the large power at the output. To match the input signal shape with larger amplitude, power amplifier takes the energy from the power supply & controls the output. In our previous article, we explain Amplifiers, Transistors, diodes, rectifiers in detail. In this article, we are going to explain Power amplifier working, performance Read More …

An amplifier is an electronic device used to boost up the strength of the weak signal. To match the input signal shape with larger amplitude, an amplifier takes the energy from the power supply and controls the output. It can either be a separate piece of equipment or an electrical circuit within another device. In our previous tutorials, we explain oscillators, transistors, semiconductors, diodes in detail. Here we are going to explain Amplifiers, amplifiers work, types etc in detail. Amplifier Theory: Amplifiers are one of the most used circuits in electronics, performs a variety of functions in a great way. Read More …
