help | |
A pulse-width modulator emits a pulse of varying width and provides | |
control over the duty cycle (high and low time) of the signal. This | |
is often used to control a voltage level. The more time the PWM | |
spends in the 'high' state, the higher the voltage. The PWM's | |
frequency/period can be controlled along with the proportion of that | |
time that the signal is high. |
