Updated On: Oct 22, 2025
- oscillator
- amplifier
- diode
- rectifier
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
An amplifier is an electronic device that increases the amplitude of an input signal, which can be either voltage, current, or power.
It boosts the strength of the signal while preserving its original waveform, frequency, and other characteristics such as phase.
Amplifiers are widely used in communication systems, audio devices, and instrumentation to enhance weak signals for further processing or transmission.
