This lecture focus to presentation on Feedback Amplifiers. Amplifier is a circuit that receives a sign at its input and also delivers an undistorted large version on the signal at its output. Amplifiers are used throughout wireless communications and broadcasting, and in audio equipment coming from all kinds. By using voltage level, amplifiers can be classified into two classes, as: Weak-signal amplifiers: these amplifiers are utilized in wireless receivers, audio tracks tape players, and disc players. A weak-signal amplifier was created to deal with exceedingly modest input signals. And Power amplifiers are utilized in wireless transmitters, transmit transmitters. A power amplifier is created to deal with large input signals.
