Claim 1
Independent Claim
115 words
A TEMPERATURE-STABILIZED DETECTOR CIRCUIT PREVENTING CLIPPING DISTORTION AT LOW SIGNAL LEVELS OF A RECEIVED SIGNAL, COMPRISING A SIGNAL-RECEIVING TRANSFORMER HAVING A SECONDARY, FIRST AND SECOND DIODES HAVING COMMON-TYPE ELECTRODES RESPECTIVELY CONNECTED TO OPPOSITE ENDS OF SAID SECONDARY, MEANS CONNECTING THE OTHER ELECTRODE OF SAID FIRST DIODE TO GROUND, IMPEDANCE MEANS CONNECTING THE OTHER ELECTRODE OF SAID SECOND DIODE TO GROUND, A LOWREACTANCE CAPACITOR CONNECTED BETWEEN GROUND AND THE FIRST-MENTIONED TYPE OF ELECTRODE OF SAID FIRST DIODE, AND RESISTANCE MEANS CONNECTED BETWEEN THE FIRST-MENTIONED TYPE OF ELECTRODE OF SAID FIRST DIODE AND A BIAS SOURCE HAVING A POLARITY TO ENABLE SAID DIODES TO PRODUCE A DETECTED OUTPUT IN RESPONSE TO SIGNALS COUPLED THERETO FROM SAID TRANSFORMER.
