Q. What are the 4 types of amplifiers?

Answer

A number of different amplifier designs are used in order to accommodate the extensive variety of applications and signals. Amplifiers may be loosely placed into one of these three categories: RF (radio-frequency) power amplifiers low-frequency power amplifiers or small-signal amplifiers. Every one of them requires a slightly different strategy when it comes to the design process because of the inherent physical limitations of the components that are utilised in the creation of the amplifier and the performances that can be achieved. This is the most important factor that contributes to the disparity. There are a number of distinct classes of amplifiers the most popular of which being Class A Class B Class AB and Class D. There are also a number of other classes.
