Question

Briefly Explain About Amplitude Demodulation.

Answer 1

Demodulation is the process of recovering the original data-carrying signal from a carrier wave. A demodulator is an electronic circuit (or software programme in the case of software-defined radio) that recovers the information content from a modulated carrier wave.

Complete answer:
In the reception of any amplitude modulated signal, demodulation is a critical step.Demodulation is the method of extracting the initial information-bearing signal from the obtained overall signal.After being modulated, the signal is transmitted through the antenna and received at the specified receiver. By simply eliminating the carrier signal, this received modulated signal was demodulated back to its original format.

Demodulation is the term for this procedure. The Demodulator is a circuit that is made up of electronic components. The destination will receive the output of this message signal.Demodulation for amplitude modulated signals can be accomplished using a variety of methods, each of which has its own set of benefits.

AM demodulators can be used in a wide range of radio devices, including broadcast receivers, professional radio communication equipment, and walkie talkies. AM is also used for air-band radio communications. Since audio is the most common application for amplitude modulation, audio is the most common output.

Note: AM demodulators are used in any piece of radio equipment that receives AM broadcasts or uses amplitude modulation in radio communications systems. Although it is not as common as it once was, amplitude modulation is still used for broadcasting on the Long, Medium, and Short-Wave bands.
