Изобретение относитс к электросв зи , устанавливаетс в абонентских аппаратах и предназначено дл восстановлени индивидуальных и групповых дельта-модулированных (ДМ) сигналов при избирательной и конференцсв и .The invention relates to telecommunications, is installed in subscriber devices, and is intended to restore individual and group delta-modulated (DM) signals during selective and conferencing.
Известен групповой декодер дл конференц-св зи, содержащий регистр сдвига, выходы которого подключены соответственно ко входам первого и второго блоков совпадени и к одному из входов триггера, другой вход которого объединен с управл ющим входом регистра сдвига, а пр мой и инверсный выходы триггера подключены к управл ющим входам первого и второго блоков совпадени , а также последо- . вательно соединенные усилитель и фильтр нижних частот П.A group decoder for a conference connection is known, containing a shift register, the outputs of which are connected respectively to the inputs of the first and second matching blocks and to one of the trigger inputs, the other input of which is combined with the control input of the shift register, and the direct and inverse outputs of the trigger are connected to the control inputs of the first and second blocks of coincidence, as well as successively. positively connected amplifier and low-pass filter P.
Однако известное устройство не дает естественности и разборчивости конференц-св зи при одновременной активности нескольких абонен2However, the known device does not give a natural and intelligible conference with the simultaneous activity of several subscribers
тов и при работе абонентов в неестественных услови х, т.е. в шлемофо нах.and when subscribers work in unnatural conditions, i.e. in the shamofo na.
Цель изобретени - повышение разборчивости речевого сигнала.The purpose of the invention is to increase the intelligibility of the speech signal.
Указанна цель достигаетс тем. что в групповой декодер дл конференц-св зи , содержащий регистр сдвига , выходы которого-подключены.соответственно ко входам первого и This goal is achieved by that in a group decoder for a conference, containing a shift register, the outputs of which are connected. respectively to the inputs of the first and
