摘要
A time domain impulse response filter may be used to equalize signals in the time domain to avoid error and artifacts that are introduced by domain transforms such as the IFFT. The disclosed time domain impulse response filter is based on the magnitude responses of the individual signals. The magnitude responses for each signal may be calculated in the frequency domain or with other techniques such as auto-regressive analysis and mathematical signal approximations algorithms, such as Padé approximations. An adaptive filter may then equalize the input sensor signals in their original time domain form using a filter calculated based on the processed signals.
