Separating apparatus for two very high frequency carriers and television transmitter comprising such an apparatus.

摘要

The invention consists in using a stabilised frequency generator (21) emitting a signal at a given frequency and frequency transposition means (22, 23, 24) receiving this signal and a composite signal containing the two carrier frequencies to be separated and delivering a composite signal containing two low-frequency carriers which are separated by two low-frequency filters (35, 36). The invention applies to television transmitters having two frequency-modulated sound channels. <IMAGE>
