BiQuad filter (IIR – filter)

With this project you can design the following filter types:
– 1st order low-pass
– 1st order high-pass
– 2nd order low-pass
– 2nd order high-pass
– Band-pass
– Band-rejection

This project includes also a documentation about how to calculate the filter coefficients of the IIR-filter algorithm in German and English language.

Furthermore you can run the project and analyze the filter output, stored inside a CSV file, based on a selectable sinusoidal input signal.

Today’s small-to-medium-sized (SMB) businesses and large enterprises are saving on their monthly communications costs by making one simple decision: to switch to a VoIP service solution from their old, outdated Plain Old Telephone Service (POTS). By choosing a new VoIP service, these companies enjoy the flexibility, reliability, call features, and audio quality that only a VoIP service can provide. Plus, they cut their phone bill by up to 70%!
