filter_sos

Version:
    Last Modified: March 15, 2017

    Applies a second-order section filter.

    Syntax

    y = filter_sos(s, x)
    y = filter_sos(s, x, d)
    Legacy name: sosfilt

    Inputs

    x

    Input signal to filter. x is a real array. If x is a matrix, the filter operates on each column of x.

    s

    Second-order section filter. s is an L-by-6 matrix. Each row of s contains the coefficients of one second-order section as [b0 b1 b2 1 a1 a2].

    d

    Dimension.

    Outputs

    y

    Filtered signal.

    % Apply filter and inverse filter
    s = [1 1 1 1 2 1; 1 2 1 1 1 1];
    x = 0:0.01:2*pi;
    y = filter_sos(s, sin(2.3*x))
