There are three types of modulation which are mentioned below:
Amplitude modulation: As the name suggests, amplitude modulation is used to modulate the amplitude of the signal. The amplitude of the carrier wave varies in accordance with the modulating signal.
Frequency modulation, FM: In frequency modulation, the form of modulation varies the frequency in accordance with the modulating signal. This type of modulation is used in various applications like telemetry seismic prospecting, radio, radar and so on.
Phase modulation: The carrier phase is varied in line with the data signal. In this modulation, frequency changes whenever the phase is changed.
Analog Communication is a data transmitting technique used to transmit data including video, audio, electrons, image etc. An analog signal is a continuous time-varying signal which represents a time-v...
