Explanation:
oscillator:
An oscillator is an electronic circuit which generates a periodic AC signal from a DC source. An oscillator has no input. The output of oscillator can be sinusoidal or Square or a triangle wave.
Modulation:
The process in which one of the characteristic parameter (amplitude, frequency, phase) of the carrier signal varies linearly with respect to message signal’s amplitude is called modulation.
