kaiser This function returns the filter coefficients of a Kaiser window. w = kaiser (m) w = kaiser (m, beta) m: positive integer value beta: real scalar value w: output variable, vector of real numbers This is an Octave function. This function returns the filter coefficients of a Kaiser window of length m supplied as input, to the output vector w. The second parameter gives the stop band attenuation of the Fourier transform of the window on derivation.
