发明名称 Method of and circuitry for detecting synchronism failure of two word sequences
摘要 A method of and a circuit arrangement for detecting synchronization of two word sequences between a measurement signal and a reference signal. The signals are applied to an exclusive OR-gate comparator whose output produces an error signal which is compared with an error signal shifted by one period. This comparison is effected by an exclusive OR-gate and in the case of coincidence, indicating that the measurement and reference signals are phase-shifted, a new synchronization is enabled. The output of the exclusive OR-gate is an error signal which is time-shifted in a shift register and multiplexer so that the time shifted bit sequence is compared with the bit sequence of the first error signal in a second exclusive OR-gate which is connected to an AND-gate for detecting coincidence and generating a further synchronization signal which is processed through counters, another AND-gate and a flip-flop to produce the synchronization signal which is applied to the reference pattern generated.
