专利附图:

摘要:Received signals are digitized by a comparator, and sampled by regeneratedclock signals synchronized to a carrier. Biphase symbol data are demodulated based onthe sampling data. A biphase decoder circuit performs subtraction of the biphase symbol

data to be paired. The subtraction result is compared with threshold values by datajudgment circuitry which then judges inversion of the biphase signals to be paired. AnRDS-ID detector circuit detects inversion of RDS signals by detection of either continuityor a ratio of signals received for a certain length period. Alternatively, RDS signals aredetected by stability of output from the pair judgment circuit to detect a combination ofbiphase symbols.
