Circuit arrangement of television transmitter intended for use in synchronous network or for synchronous operation of television translators with linear conversion of frequency

摘要

In the invented Circuit arrangement of television transmitter intended for use in synchronous network, particularly in a synchronous network of at least two transmitters or synchronous operation of television translators with linear conversion of frequency, the output of a primary signal receiving antenna (1) is connected to the input of a filter with a synchronizing element (2) the output of which is connected to a mixer (3) input, whereby said mixer (3) output is connected to the input of an output amplifier (6). Said amplifier (6) output is connected to the input of a terminal power amplifier (7), the output of which is connected to the input of a selective channel filter (8). Said selective channel filter (8) output is then connected to the input of a transmitting antenna system (9), wherein one output of an auxiliary oscillator (4) is connected to said mixture (3) input and another output of said auxiliary oscillator (4) is connected to said output amplifier (6) input the another output thereof is connected to said filter with the synchronizing element (2).
