Empfangsvorrichtung für winkelmodulierte Signale |
摘要 |
The invention relates to a receiving device for angle-modulated signals. Channels are not selected in an analogue but a digital manner (10, 11). To this end, a receiving signal is preferably converted to an intermediate frequency band ( omega ZF), filtered and A/D converted. The receiving signal is subsequently converted to the baseband and channels are selected in a digital manner by means of a digital complex multiplier (9) before the receiving signal portion of the selected transmission channel is demodulated and the corresponding signals are detected by means of a differential demodulator (12).
