Abstract

The present invention discloses an apparatus for minimizing the effects of destructive interference caused by multipath fading. An amplitude sensing module receives IF signals from a plurality of receivers and generates high speed voltage signals proportional to the logarithm of the amplitude of each of the IF signals. An analog logic module compares the high speed signals to each other to determine the high speed voltage signal having the greater level and actuates a switch to select the audio output from the receiver having the high speed signal with the higher voltage level. The switched audio output of the analog logic module is filtered by an output filter module to remove switching transients generated within the analog logic module. The filter module is programmable to accommodate various IF bandwidths and response characteristics.
