| Pulse modulation | 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. |
