Abstract
A method, computer program, and apparatus for compensating for group delay. The method comprises the steps of generating a raw step response of a system, differentiating the raw step response to generate an impulse response of the system, windowing the impulse response and taking a Fast Fourier Transform (FFT) of the windowed impulse response to generate a frequency response of the system. A phase response of the system is then calculated from the frequency response, and an IFFT Group Delay filter is defined in accordance with the phase response of the system. Finally, the IFFT Group Delay filter is applied to the raw step response.
