Декодер абонентской системы телевидения относится к телевизионной технике и может найти применение в системах с засекречиванием телевизионного сигнала. Для расширения функциональных возможностей декодера абонентской системы телевидения фильтр в цепи первого канала телевизионного приемника (ТВП) выполнен согласованным с кодовой посылкой телевизионного сигнала и перепрограммируемым, например в виде программируемого фазоманипулированного фильтра на ПАВ, последовательно с одним из входов мультиплексора включена линия задержки, величина которой выбрана пропорциональной времени задержки сигнала в согласованном фильтре, сигнальный вход усилителя подключен к выходу мультиплексора, управляющий вход усилителя - к второму выходу формирователя, а выход усилителя - к входу ТВП.The decoder subscriber television system relates to television technology and can be used in systems with the secrecy of the television signal. To extend the functionality of the decoder subscriber television system, the filter in the first channel circuit of the television receiver (TVP) is made consistent with the code signal of the television signal and reprogrammed, for example, in the form of a programmable phase-controlled filter on SAW, a delay line is included in series with one of the multiplexer inputs proportional to the delay time of the signal in the matched filter, the signal input of the amplifier is connected to the output of the multiplexer, control The input of the amplifier is for the second output of the driver, and the output of the amplifier is for the input of the TVP.
