Using high-IF sampling A/D converters beyond baseband frequencies

In the simplest analog receive signal path, the antenna feeds a low-noise amplifier (LNA), which in turn feeds an analog-to-digital (A/D) converter, which then feeds a digital processor. In all but ...

Audio sampling

For the most part, the mechanisms of the natural world around us, including sound, operate in the analog domain. And so the transducers used to convert sound into electrical signals (microphones) and ...
