Pulse Width Modulation |
|---|---|
|
Changes the position of pulses to encode information. |
Changes the pulse width to encode information. |
|
Adjusts the pulse’s location within a time interval. |
Alters the pulse’s breadth or duration |
|
It is highly sensitive to timing variations |
It is less sensitive to timing variations |
|
It is usually calls for more bandwidth than PWM |
It can required more bandwidth-efficient in certain scenarios |

Example : Motor Control System, Audio System |
Pulse Width Modulation (PWM)
In Electronic Engineering, Pulse Width Modulation, or PWM, is a commonly used technique for effectively controlling the power supplied to electrical devices. In order to attain a desired average voltage or power level, the principle of pulse width modulation (PWM) is used for a periodic signal, which is usually a square wave.
A key component of pulse width modulation (PWM) is the duty cycle, which is defined as the ratio of the pulse width to the whole time period. An increase in the duty cycle translates into an increase in average power output. Basically, PWM is used to obtain analog signals from digital services- for instance, the microcontrollers and it represents the amplitude of an analog signal input signal.
