Abstract
A signal processing apparatus configured to correct a distortion introduced by a signal processing path into a processed signal comprising a transformer that transforms the processed signal into a transformed signal in frequency domain, a processor that determines a first correction function and a second correction function upon the basis of a transfer function of the signal processing path, a first multiplier that multiplies values of the transformed signal with coefficients of the first correction function to obtain a first corrected signal, a signal reverser that reverses an order of values in a copy of the transformed signal to obtain a reversed transformed signal, a second multiplier that multiplies values of the reversed transformed signal with coefficients of the second correction function to obtain a second corrected signal, and an adder that adds the first corrected signal and the second corrected signal to obtain a corrected output signal.
