(contracted; show full)e frequencies. While the human ear is not sensitive to the phase of audio frequencies (involving delays of less than 1/30 second) in most non-audio applications the actual [[waveform]] of the transmitted signal must be preserved, not just its frequency content. Thus these equalizing filters must also cancel out any phase shifts (unequal delay) between different frequency components.
