 % * Flipped order of FIR coefficients:
-%   The FIR coefficients in the PFB are flipped per column of N_fft = 1024
+%   The FIR filter in the PFB is defined by a prototype filter h[] with N_fft
+%   * N_taps = 1024 *16 = 16384 coefficients. The impulse response of this
+%   prototype filter will show the coefficients in h[0:16383] order. The
+%   FIR coefficients of h[] in the PFB are flipped per column of N_fft = 1024
 %   coefficients, for all N_taps = 16 columns. In VHDL simulation this shows
 %   with tb_verify_pfb_response.vhd and in the Matlab model this flip is also
 %   done by ctrl_pfir_subband.coeff = flipud(ctrl_pfir_subband.coeff).
