The receiver preferably serves to receive transmitted radio-frequency radio time signals with amplitude modulation. The received broadband, impedance-converted radio-frequency signal is forwarded to the self-oscillating circuit which comprises a differential amplifier with outer connections. The audio-frequency-converted and frequency-modulated output signal is fed directly to the microprocessor and is evaluated using statistical methods, in particular cross-correlation. The dynamic response of the reception circuit can be regulated via digital outputs. Despite its very high resistance to interference, the receiver can be manufactured at low cost and monolithically integrated. |
