Abstract
A radio signal will often suffer from amplitude and group delay distortion caused by multipath fading. An adaptive equalizer, which effectively cancels the amplitude distortion effects, is based upon the use of control voltages derived from selected portions of the IF band; the control voltages being selectively applied to bump and slope equalizer sections to cancel the effects of amplitude distortion. Cancellation of group delay distortion is predicated upon its being proportional to amplitude of the slope correction required. Thus, group delay correction is introduced in relation to the slope correction introduced to compensate for distortion introduced during normal multipath propagation conditions.
