Abstract: 1407683 Synchronizing systems; multiplex pulse signalling NIPPON HOSO KYOKAI and NIPPON ELECTRIC CO Ltd 13 Nov 1972 [12 Nov 1971 (3)] 52369/72 Headings H3A and H4L An arrangement for synchronizing an oscillator 11 at a remote station 10, 20 or 30 with an oscillator 51 at a base station 50 comprises a phase detector 561 at the base for comparing a received first signal with the base oscillator output, a phase shifter 562 responsive to the detected phase difference for phase shifting the first signal into synchronism with the oscillator output and an arrangement (81-84, Fig. 2) for deviating the frequency of remote oscillator 11 in a direction tending to invert the sign of the phase difference detected at the base. Control of the remote station may be accomplished via a limit detector 60 and transmitter receiver control arrangements or by human operators over telephone lines. In operation, as soon as the detected phase difference reaches a limit, the resonant frequency of the remote oscillator is altered to a higher or lower frequency by an applied control signal for causing the phase difference to rapidly attain its other limit. When the resonant frequency is switched back to its central value, the phase difference can drift once again to its first limit. The oscillators 11, 51 may supply the colour sub-carrier signal for TV transmission or the clock pulse for PCM transmission while the sync generators 14, 53 supply a group of synchronizing signals. In the circuit of Fig. 2, the output of a VCO 71 is phase modulated at 72 by a low frequency oscillator 73 and when the multiplier 75 output coincides with the resonant frequency, absorption of a light beam at the resonant frequency takes place and the demodulated output is phase compared at 78 with the output of oscillator 73 for the synchronization of VCO 71.
