IIR Filters

iirhigh(C, f) Returns coefficients for a highpass IIR filter with cutoff frequency f. The input array C is generated by one of the IIR filter coefficient functions.

iirlow(C, f) Returns coefficients for a lowpass IIR filter with cutoff frequency f. The input array C is generated by one of the IIR filter coefficient functions.

iirpass(C, lowf, highf) Returns coefficients for a bandpass IIR filter with cutoff frequencies lowf and highf. The input array C is generated by one of the IIR filter coefficient functions.

iirstop(C, lowf, highf) Returns coefficients for a bandstop IIR filter with cutoff frequencies lowf and highf. The input array C is generated by one of the IIR filter coefficient functions.
