Band reject IIR filter
IIR band reject filter
"Band reject IIR filter" applies an IIR band reject filter to the given signal x.
Its parameters are
- Filter design method:
- "Butterworth" (0)
- "Chebyshev" (1)
- "Elliptic" (2)
- Filter order n
- Pass band ripple in dB (Chebyshev and Elliptic only)
- Attenuation atten in negative dB (Elliptic only)
- Lower stop band edge frequency f0 in reciprocal units of the x-axis
- Upper stop band edge frequency f1 in reciprocal units of the x-axis
y = IIRBandReject(x,method,n,ripple,atten,f0,f1);
Band pass IIR filter, Low pass IIR filter, High pass IIR filter.
