Modulators

Assertion: AM detection is the process of recovering the modulating signal from amplitude modulated waveform wich is carried out using a rectifier and an evelope detector. Reason: Amplitude modulated waves can be produced by application of the message signal and the carrier wave to a non-linear device followed by band pass filter.

Modulation is the phenomenon of :

Modulation is done in

Amplitude modulation is the process of

Modulation is not used to :-

Write two basic modes of communication. Explain the process of amplitude modulation. Draw a schematic sketch showing how amplitude modulated signal is obtained by superposing modulating signal over a sinusoidal carrier wave.

A: Transducer in communication system converts electrical singal into a physical quantity. R: For information signal to be transmitted directly to long distances, modulation is not a necessary process.
