Description
II
Изобретение относитс к электросв зи и может быть использовано при передаче дискретной ин(|юрмации по телефонным каналам.The invention relates to telecommunications and can be used in the transmission of discrete information (| yurmatsii over telephone channels.
Известно устройство дл измерени фазовых искажений каналов св зи, содержащие на передающей стороне генератор испытательных сигналов, выход которого подключен к входу канала св )зи, а на приемной стороне полосовой (|)ильтр, выход которого подключен к Индикатору, коррел тор и блок синхронизации fl .A device for measuring phase distortions of communication channels, containing on the transmitting side a generator of test signals, the output of which is connected to the input of the communication channel, and on the receiving side of the band pass (|) illuminator, the output of which is connected to the Indicator, the correlator and synchronization unit fl .
Однако известное устройство обладает низкой точностью измерений, обусловленной погрешност ми, вносимыми при коррел ции и синхронизации испытательного сигнала.However, the known device has a low measurement accuracy due to errors introduced during the correlation and synchronization of the test signal.
изобретени - повышение точности измерений. invention - improving the accuracy of measurements.
Дл достижени указанной цели в устройство дл измерени фазовых искажений , содержащее на передающей стороне генератор испытательных сигналов , выход которого подключен к входу канала св зи, на приемной стороне - полосовой фильтр, выхрд которого подключен к входу индикатора, на приемной стороне введены переключатель, блок эталонных искажений, блок ав . томатической регулировки уровн , квадратор , фильтр посто нной составл ющей, второй генератор испытательных сигналов , при этом .выход канала св зи To achieve this goal, a device for measuring phase distortions, containing on the transmitting side a test signal generator, the output of which is connected to the input of the communication channel, on the receiving side is a band-pass filter, the output of which is connected to the input of the indicator; distortion block av. level adjustment, quad, dc filter, second test signal generator, while the output of the communication channel
10 подключен к входу полосового фильтра через последовательно соединенные переключатель, блок эталонных искажений , блок автоматической регулировки уровн и квадратор, выход которого 10 is connected to the input of a band-pass filter through a series-connected switch, a reference distortion unit, an automatic level control unit and a quad, the output of which
IS через фильтр посто нной составл ющей подключен к другому входу блока автоматической регулировки уровн , второй вход переключател соединен с выходом второго генератора испыта39 тельных сигналов.The IS is connected via a DC filter to another input of the automatic level control unit, the second input of the switch is connected to the output of the second test signal generator.
