Function FILTER_FREQ

Package

filters

Short description

Calculate center frequencies and bandwidths

Usage 

    [psi_xi, psi_bw, phi_bw] = FILTER_FREQ(filt_opt)

Input 

    filt_opt (struct): The parameters defining the filter bank.

Output 

    psi_xi (numeric): The center frequencies of the wavelet filters.
    psi_bw (numeric): The bandwidths of the wavelet filters.
    phi_bw (numeric): The bandwidth of the lowpass filter.

Description 

    Called by WAVELET_1D and WAVELET_LAYER_1D, this function provides the
    center frequency and bandwidth of a mother wavelet, whose parameters
    are specified in filt_opt. It operates as a mere disjunction between
    SPLINE_FREQ_1D, and MORLET_FREQ_1D.
