iir_yulewalker

Version:
    Last Modified: March 15, 2017

    Uses the modified Yule-Walker method to create an IIR filter.

    Syntax

    [x, y] = iir_yulewalker(n, f, a)
    Legacy name: yulewalk

    Inputs

    n

    Filter order.

    f

    Vector of frequency points. f is a real vector of non-descending values in the interval [0, 1]. 1 represents the Nyquist frequency.

    a

    Magnitudes of the filter at the frequency points in f. length(a) must equal length(f).

    Outputs

    x

    Forward coefficients of the IIR filter. The length of x equals n + 1.

    y

    Backward coefficients of the IIR filter. The length of y equals n + 1.

    f0 = [0, 0.2, 0.4, 1];
    a0 = [1, 1, 0, 0];
    [x0, y0] = iir_yulewalker(8, f0, a0);
