Certain types of low-level DC signals can present a challenge when trying to digitize using the internal analog-to-digital Converter (A/D) commonly found on many microcontrollers. These A/Ds typically ...

(Editor's Note: There are links to the previous parts of this series at the end, below the author's biography.) For all signal-chain devices to operate properly, each requires a stable-voltage power ...

1. This optimised analogue-conditioning circuit can avoid signal distortion caused by nonlinearities, and guarantee an optimum interface between the encoder and ADC. 2. shown is a normalised RC filter ...
