<p>: The dispersive effects of frequency selective fading in a digital, FM, or AM radio system are reduced by means of an adaptive equalizer comprising a cascade of feed-forward stages, each of which includes: a first parallel wavepath including a first adjustable attenuator; a second parallel wavepath including a second adjustable attenuator and delay device a combiner is provided for combining the signals in the wavepaths and for coupling the combined signal to the next stage. By a suitable selection of parameters, according to two unique relationships, a transfer function can be realized which can compensate for amplitude and delay distortions caused by minimum and nonminimum phase fades.</p> |
