Digital filters for offset removal. The Atmega ADC (Arduino) has an input voltage range of 0 to V cc and so when sampling an AC waveform the waveform needs to be biased at V cc / 2. This translates to a digital offset value of approximately 512. The waveform sample digital value will be between 0 and 1023, centered around 512.

Digital Filter Types in Delta-Sigma ADCs Some data converters have slightly modified sinc filters. In some industrial applications, power utility interference pollutes the environment of the equipment at 50 Hz or 60 Hz. A digital filter that has notches

Tutorial: Potentiometers with Arduino and Filtering. The higher the input voltage, the larger the digital value. Arduino’s ADC takes in 0 to 5 volts and has a 10-bit resolution which lets it output 1024 digital values. To summarize: 0 volts is equivalent to a digital value of 0, and 5 …
Digital filter design with Arduino DUE and Matlab
This] is a very good book on digital filters, and it is available online for free. I doubt I can explain the filter operation better than the author of that book. However, I have implemented the Recursive Bandpass filter on an arduino, which might be useful to others.
