摘要： When demodulated signals through respective paths are combined by a data combiner, with write addresses of count values of PN phase counters that represent the phases of the PN codes of fingers, the demodulated signals that are output from the fingers are stored in memories. With a common read and combined to form a single demodulated signal address, signals stored in the memories are read.

摘要： A synthesis signal which was reproduced from reproducing apparatus and converted into an analog signal includes an analog information signal and a copy control code. The copy control code is modulated by a spread spectrum. A code reading unit of the recording apparatus extracts the copy control code by an inverse spread spectrum. A code changing unit changes the copy control code by a spread spectrum as necessary. An output signal of the code changing unit is converted into a digital signal. The digital signal is subjected to processes necessary for recording and is recorded to a recording medium.

摘要： A frequency modulated signal demodulator circuit wherein an in-phase component (I) and an orthogonal component (Q) of a frequency modulated signal output from an orthogonal detector circuit are respectively delayed by one sampling time. The result (I.multidot.Qs) of multiplying the in-phase component (I) by a delayed orthogonal component (Qs) is subtracted from the result (Q.multidot.Is) of multiplying the orthogonal component (Q) by the delayed in-phase component (Is), and the subtraction result (d.theta.) is multiplied by an inverse (1/Ts) of the sampling time to derive an instantaneous angular frequency (d.theta./Ts), whereby the frequency modulated signal can be demodulated without any feedback loop which is required by conventional FM demodulator circuits, thus making it possible to avoid a deterioration demodulation characteristics due to the influence of phasing.
