Digital bandpass filter design3/9/2024 ![]() Spectral inversion flips the frequency response top-for-bottom, changing the passbands into stopbands, and the stopbands into This results in the high-pass filter kernel shown in (c), with the frequency Second, add one to the sample at the center of symmetry. Two things must be done to change the low-passįilter kernel into a high-pass filter kernel.
