A circuit for processing reflected signals is described. The reflected signal is delayed for a period of time which is equal to the period of the first half cycle of the reflected signal. It is also attenuated by an amount equal to the difference in amplitude between the first and second half cycles of the reflected signal. The delayed and attenuated signal is then combined with the reflected signal so that only the first half cycle of the reflected signal and the last half cycle of delayed signal remain.
