PWM The duration of on time is called the pulse width. To get varying analog values, you change, or modulate, that pulse width. If you repeat this on-off pattern fast enough with an LED for example, the result is as if the signal is a steady voltage between 0 and 5v controlling the brightness of the LED.In the graphic below, the green lines represent a regular time period.he duration of on time is called the pulse width.
