||Continuous wave modulation
|The modulated signal is in the form of pulses.
||The modulated signal is in the form of continuous signals.
|It is used sampling technique.
||It is not used sampling technique.
|It has required large bandwidth.
||It has required less bandwidth.
|Pulse modulation has both analog and digital nature.
||It has only analog modulation.
|In pulse modulation, the train of pulses is used as a carrier.
||High frequency sine wave is used as carrier.
|The input signal is either analog or digital.
||Input signal is analog signal only.
|The example of pulse modulation is PAM, PPM, PWM, DPCM, ADM etc.
||The example of continuous wave modulation is AM (amplitude modulation), FM (frequency modulation) and PM (pulse modulation).
|It is used in satellite communication.
||It is used in radio and TV broadcasting.
