State Variable Filters

Click here to return to the Algorithm Information page

The State-Variable filter offers lowpass, highpass, bandpass, and band-reject all within one block.

An added advantage over biquad section filters is that only one coefficient is needed, rather than their five coefficients. For the algorithm including Q, there's an additional coefficient for its control.
