Изобретение относитс к радиотехнике и может использоватьс в каналах записи-воспроизведени видеомагнитофонов.The invention relates to radio engineering and can be used in recording / reproducing channels of video recorders.
Известен апертурный корректор канала записи-воспроизведени видеомагнитофонов, содержащий два потенциометра, первый из которых соединен со входом линии задержки. Известное устройство требует сложной схемной реализации.A known aperture equalizer of the recording-reproduction channel of video recorders, containing two potentiometers, the first of which is connected to the input of the delay line. The known device requires a complex circuit implementation.
Цель изобретени - упрощение устройства. Дл этого в предлагаемом устройстве выход линии задержки защунтирован вторым потенциометром , а выход устройства подключен ко входу линии задержки.The purpose of the invention is to simplify the device. For this, in the proposed device, the output of the delay line is ground by the second potentiometer, and the output of the device is connected to the input of the delay line.
На чертеже изображена принципиальна схема устройства.The drawing shows a schematic diagram of the device.
Оно содержит последовательно соединенные первый потенциометр 1, линию задержки 2 и второй потенциометр 3.It contains connected in series the first potentiometer 1, the delay line 2 and the second potentiometer 3.
Устройство работает следующим образом.The device works as follows.
Поступающие на вход синусоидальные составл ющие сигнала отражаютс на вход линии задержки 2 с различным сдвигом по фазе относительно падающей волны. Взаимодействие падающей и отраженной волны позвол ет получить на выходе устройства требуемую амплитудно-частотную характеристику входного сигнала.The sinusoidal input components of the signal are reflected to the input of delay line 2 with a different phase shift relative to the incident wave. The interaction of the incident and reflected waves allows to obtain at the output of the device the required amplitude-frequency characteristic of the input signal.
