Generation of Amplitude Modulation

This Lab Tutorial is for generation of amplitude modulation. It is such a modulation technique where the amplitude of a high frequency carrier signal is varied with respect to message/base band signal.

Amplitude modulation is defined as the process in which is the amplitude of the carrier wave is varied about a means values linearly with the base band signal. The envelope of the modulating wave has the same shape as the base band signal provided the following two requirements are satisfied:

1.    The carrier frequency fc must be much greater than the highest frequency components fm of the message signal m (t) i.e. fc >> fm
2.    The modulation index must be less than unity. if the modulation index is greater than unity, the carrier wave becomes over modulated.
