Synopsis

Design an IIR filter consisting of up to three parts (high-pass, low-pass and notch) and apply it as part of the signal-processing chain. To use it as a bandpass, specify the desired lower end of the band as a high-pass corner, and the desired upper end of the band as a low-pass corner.

Parameters

HighPassCorner

High-pass cutoff frequency. The default is 0, which disables the high-pass.

HighPassOrder

Filter order for the high-pass. The default is 2. A value of 0 disables the high-pass.

LowPassCorner

Low-pass cutoff frequency. The default is 0, which disables the low-pass.

LowPassOrder

Filter order for the low-pass. The default is 4. A value of 0 disables the high-pass.

NotchCenter

Notch center frequency. The default is 0, which disables the notch filter.

NotchOrder

Filter order for the notch. The default is 4. A value of 0 disables the notch filter.
