Phase equalization is performed keeping in mind that distortion-less transmission occurs in systems having rectangular magnitude with linear phase response. However, in the real world, the linear phase requirement is often too strong. It is expectable that larger phase error can be tolerated in frequency regions corresponding to higher attenuations. Therefore, setting the appropriate requirements...
One application of all-pass systems is phase equalization. Such equalization is usually performed to reduce waveform distortion of a signal passed through a system. Well known methods for equalizer design are derived in the frequency domain. Here, we present an approach which is based on the time-domain synthesis. We start from waveform distortion defined as the maximum value of the correlation between...
