Introduction
The use of pulse-width modulation (PWM) continues
to increase with the rise in digital control logic. Pulse
width modulation offers a simple method for digital
control logic to create an analog equivalence. Many
micro-controllers have PWM capability built-in. PWM
is also used in communication systems, since a digital
signal ismore robust and less vulnerable to noise.
This application note provides a brief overview of
PWM and offers ideas on how to use a function
generator to create pulse-width modulated signals.
