Abstract:
A signal timing device, comprising:an antenna for receiving an input signal;a detector adapted to provide from said input signal a first signal having one selected characteristic indicating that said input signal was propagated along a direct path from a remote location to said antenna and a second signal having another selected characteristic indicating that said input signal was propagated along an indirect path from said remote location to said antenna;a plurality of logic circuits to receive said first and second signals separately and operating synchronously to determine a first power level representation for said first signal and a second power level representation for said second signal;a comparator adapted to compare said first and second power level representations; anda timing circuit adapted to provide timing information if the first power level exceeds the second power level and selectively to provide or not provide timing information if the second power level exceeds the first power level.
