METHOD AND DEVICE FOR RECEIVING FREQUENCY-MODULATED ANALOG SIGNALS WITH DIGITAL PROCESSING

The method consists in directly converting a frequency-modulated analog signal by purely digital methods into a numerical code ( DELTA N) proportional to the deviation ( DELTA f) of the signal of the intermediate frequency (f). The device for implementing the method comprises a converter (1), a comp...

Zusammenfassung:The method consists in directly converting a frequency-modulated analog signal by purely digital methods into a numerical code ( DELTA N) proportional to the deviation ( DELTA f) of the signal of the intermediate frequency (f). The device for implementing the method comprises a converter (1), a comparator (3), a frequency divider (5), a pulse duration measuring unit (6), a processor (7), a signal dividing unit (8) and a generator (9) of synchronizing pulses.
