Description
II
, Изобретение относитс к радиотехнике и может использоватьс дл передачи музыкальных и речевых программ по аналоговым каналам св зи, в частности по междугородним каналам звукового вещани (МКЗВ).The invention relates to radio engineering and can be used to transmit music and speech programs over analog communication channels, in particular, over long-distance audio broadcasting channels (ICTV).
Известно устройство дл передачи и приема программ звукового вещани , содержащее на передающей стороне последовательно соединенные входной согласующий блок, блок стабилизации уровн и преобразователь спектра, а на приемной стороне входной согласующий блок, выход которого подключен к входу преобразовател спектра, блок стабилизации уровн и выходной согласующий блок 1A device for transmitting and receiving audio broadcasting programs is known, comprising on the transmitting side a serially connected input matching unit, a level stabilization unit and a spectrum converter, and on the receiving side an input matching unit whose output is connected to the input of the spectrum converter, a level stabilizing unit and an output matching unit one
Однако известное устройство имеет низкую помехозащищенность.However, the known device has a low noise immunity.
Цель изобретени - повышение помехозащищенности .The purpose of the invention is to improve the noise immunity.
Поставленна цель достигаетс тем, что в устройство дл передачи и приема программ звукового вещани .This goal is achieved by the fact that a device for transmitting and receiving audio broadcasting programs.
содержащее на передающей стороне последовательно соединенные входной согласующий блок, блок стабилизации уровн и преобразователь спектра, а на приемной стороне - входной согласующий блок, выход которого подключён к входу преобразовател спектра, блок стабилизации уровн и выходной согласующий блок, на приемной стороне введены блок динамической фильтрации , пороговый блок и блок селекции , выход которого подключен к входу блока стабилизации уровн , выход которого через пороговый блок соединен с входом блока динамической (фильтрации, выход которого подключен к входу выходного согласующего блока, при этом выход преобразовател спектра соединен с входом блока селекции.containing on the transmitting side a serially connected input matching unit, a level stabilization unit and a spectrum converter, and on the receiving side an input matching unit, the output of which is connected to the input of the spectrum converter, a level stabilization unit and an output matching unit, at the receiving side a dynamic filtering unit is inserted, the threshold unit and the selection unit, the output of which is connected to the input of the level stabilization unit, the output of which through the threshold unit is connected to the input of the dynamic unit (filtering , the output of which is connected to the input of the output matching unit, while the output of the spectrum converter is connected to the input of the selection unit.
