Abstract: PROBLEM TO BE SOLVED: To decrease the probability of erroneous detection and to shorten the time of establishment by generating a spreading code according to a frequency-divided basic clock, inversely spreading that code, cumulatively adding it or each address and establishing the synchronism of a maximum correlative value. SOLUTION: The clock of a frequency equal with spread spectrum is frequency- divided by a frequency divider 10 and applied to a spreading code generator 5 and the same code is outputted for one cycle of the spreading code. Corresponding to this output, the received spread signal is inversely spread by a multiplier 1, cumulatively added by an adder 2 and stored in a cumulative memory 12. Based on the output of an address counter 11 shifted chip by chip for each cycle, address designation is performed to this signal. The maximum correlative value is detected by a maximum correlative value detector 7, synchronism is established, the correlative value of a correspondent address in the cumulative memory 12 is held in a correlative value latch circuit 8, and the phase is held in a phase latch circuit 9. This phase information is used for inversely spreading main received signal data.  Thus, the probability of erroneous detection on a transmission line, where instantaneous fluctuation occurs, is reduced and the time for establishment can be shortened.

IPC: G10H1/043
Filed: 1988-11-09
Abstract: PURPOSE:To improve total period resolution by varying the period of only a k-th part among (m) divisions of one repetitive waveform period and adjusting a mean period finely. CONSTITUTION:Waveform data is stored in a waveform ROM 105, which is accessed at a constant frequency fA according to the output of a program counter 101, but the output data of a scale ROM 104 is varied at k-th timing in access to the waveform of one cycle to vary a frequency division ratio instantaneously. Consequently, pulses of fA differ in period instantaneously. The waveform ROM 105 is accessed with the pulses and the read data is passed through a D/A converter 106, so that a person recognizes pulses of different frequency. Consequently, a sound generator is obtained which can use not a high frequency oscillator, but a low frequency oscillator so as to obtain a vibrate frequency requiring high resolution.
