SIGNALEMPFÄNGER ZUM EMPFANG VON SIGNALEN, DIE VON EINER SONDE AUSGESENDET WERDEN

摘要

A pulse signal receiving system for receiving signals transmitted from a probe (10) comprises a transmitter (16) associated with the probe (10), a plurality of receivers (18,18') for receiving signals transmitted by the transmitter and a circuit (22) connected to receive the output signals of said receivers (18,18'). Said circuit (22) compares the signal strengths of the signals from each receiver and selects an output from one or more of the receivers based on the relative signal strengths thereof. Said circuit (22) also includes a circuit for combining and averaging the receiver output signals (58) and for selecting an output signal when it exceeds the average.
