Those following the ProtoStack tutorials will be happy to hear that there is a new installment which explains Pulse Width Modulation. If you’ve never heard of PWM before, it’s a method … ...

Pulse amplitude modulation (PAM) is already a widely adopted technology in high-speed digital communications. But to understand why it has become ubiquitous in serial data standards, you first must ...

PDM — pulse density modulation — is similar to PWM and, like PWM, requires a filter that could range from a simple RC network to an active filter. You can see the result in the video below.
