Abstract
A variable group delay equalizer comprises a delay portion and an amplitude correcting portion. In the delay portion, a group delay frequency response of an input signal is controlled. In the amplitude correcting portion, an amplitude distortion of the input signal caused in a delay portion can be corrected. A variable group delay equalizer with a wider variable range can be obtained by combining a fixed group delay equalizer.
