Patent GB-1491664-A (GB)
Title: Frequency converters
IPC: H03G3/10
Filed: 1976-06-11
Abstract: The frequency converter has active modulators which contain transistors as the modulating elements. The carrier generators (6) are provided with a monitoring device which, in particular operating modes in which the carrier-frequency accuracy required for interference-free carrier-frequency signal transmission is not guaranteed, responds and transmits a control criterion. In processing the carrier frequencies via crystal oscillators which are synchronised by means of a phase-locked loop with a control frequency of very high precision, unacceptably high frequency deviations may occur in the event of a synchronisation fault - e.g. control frequency failure. To the same extent as the carrier-frequency deviations, a displacement of the channel groups occurs during conversion. The 4 kHz spacing can be displaced to such an extent that channels from the malfunctioning converter stages enter frequency ranges which may be occupied by intact channels and interfere with them. To prevent interference of this type, the frequency converter is designed in such a way that switching modulators (11, 12, 13 and 14) which operate multiplicatively and are fed with an impressed direct current are deactivated by means of control criteria through extraction of the direct current from the modulating transistors (11, 12, 13, 14). This results in very high attenuation of the sideband and transmission is thereby interrupted. <IMAGE>
