A. Modulation
B. Oscillation
C. Amplification
D. Purification
Answer: Option D
Solution(By Examveda Team)
The most common function of a diode is to allow an electric current to pass in one direction (called the diode’s forward direction), while blocking current in the opposite direction (the reverse direction).This unidirectional behavior is called rectification or verification and is used to convert alternating current to direct current, including extraction of modulation from radio signals in radio receivers— these diodes are forms of rectifiers diode is a two terminal electronic component with an asymmetric transfer characteristic, with low (ideally zero) resistance to current flow in one direction, and high (ideally infinite) resistance in the other.This Question Belongs to General Knowledge >> Physics
