Amplitude Modulation

Production Of Amplitude Modulated Wave

The maximum and minimum amplitude of an amplitude modulated wave is 16V and 8V respectively. The modulation index for this amplitude modulated wave is "x"xx10^(-2) . The value of x is "_____"

The frequency of amplitude modulated wave is equal to

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.
