A common PC sound card can be used as a sine/square/triangle function generator, but the output suffers from limited rail-to-rail swing, plus its zero-centered has no dc offset. This circuit overcomes ...

In IC design, the typical approach for generating a pulse width-modulated (PWM) signal from an analog value (such as in the control loop for a switch mode power supply) uses a ramp or triangle wave ...

Chinese Digital PWM modules have come down in cost over the past few months, but picking a PWM module that will help you to do what you need actually means you have to think about a host of things, ...
