Examples
ocmsp_iir_filter_ss
Design digital or analog IIR filters with given specifications. It returns filter represented in state-space form.
Examples
ocmsp_iir_filter_zp
Design digital or analog IIR filters with given specifications. It returns the zeros, poles and the gain.
Examples
ocmsp_iir_order
Estimate the minimum order of a digital/analog IIR filter required to meet a set of filter design specifications: loses no more than Rp dB in passband and has at least Rs dB of attenuation in the stopband.
Examples
