Antenna diversity receiving system for eliminating reception interference in mobile television signal reception

Abstract From the Canadian patent

Antenna diversity receiving system for mobile reception of television signals having N antenna inputs, one diversity processor with as many inputs, and connected downstream in the system to a television receiver, the video signal of the television receiver and the line and picture synchronizing signals being applied to the diversity processor. The diversity processor comprises a time gate circuit which is opened by the line synchronizing pulses during the line blanking interval and switches the video signal through to the signal quality evaluation circuit. At that location an output signal having the signal quality of the video signal is produced which is applied to the control …
