Question

Draw the block diagram of a receiver of AM radio wave. Explain each of the components used.

Accepted Answer

AM receiver – Amplitude modulation receiver is electrical equipment that receives an amplitude modulated wave as input and produces the original signal as an output.

The basic description of all the parts of the AM receiver is as follows-

Receiving antenna – A receiving antenna functions opposite to a transmission antenna and receives the amplitude-modulated wave and converts it into electric current and feeds it to the amplifier.

Amplifier – An amplifier is a piece of equipment that is used to amplify the signal received by the antenna.

IF stage – In the intermediate-frequency amplifier stage the intermediate frequencies of the amplified signals are filtered and amplified before feeding it the demodulator, this makes the process of demodulation easier.

Detector – It is a device or circuit, used to extract the desired signal from the carrier wave, a process called demodulation

Amplifier- It is a component that amplifies the low power electric signals that have become low after the IF stage and the process of demodulation.

This signal can now be used for the desired device (maybe a TV or a radio).
