ABSTRACT:
An amplitude equalizer is provided for equalizing amplitude distorted signals within a predetermined frequency band. The amplitude equalizer comprises first means for splitting signals into first and second split signals. A first delay device receives one of the two split signals, and a second signal splitter splits the output of the first delay device into third and fourth split signals, the third split signal being applied to a second delay device having a delay equal to the delay of the first delay device. The output of the second delay device is combined with the second output from the first signal splitter in a first signal combiner, the output of which is applied to a circuit for adjusting the polarity and gain of the signal applied thereto. The output of the polarity and gain adjusting circuit is applied to a second signal combiner which combines the adjusted signal with the fourth output from the second signal splitter to thereby provide equalized signals. As organized above, the equalizer can provide for arbitrary selection of the desired frequency regions and maximium equalized amplitude by simply varying either the amplitude or attenuation factor, and by properly choosing the delay time. Further, equalization of secondary and higher order distortion can be achieved by virtue of constant delay over the entire frequency region.
