Description
стандартной строки, поступает на элемент 1 задержки и на амплитудный селектор 2. Последний вьщел ет строчный синхроимпульс, который затем умножаетс в умножителе 4 частоты и синхро11изируетс генератором 5 импульсов, который выдает последовательность тактовых импульсов.A standard line arrives at delay element 1 and at amplitude selector 2. The latter selects a horizontal sync pulse, which is then multiplied in frequency multiplier 4 and synchronized by a pulse generator 5, which outputs a sequence of clock pulses.
.Число импульсов в последовательности соответствует числу конденсаторов кольцевого накопител элемента 1 задержки . Этой импульсной последовательностью управл етс переключатель в элементе 1 задержки, осуществл ющий считывание видеосигналов с конденсатеров . Придем йигнал на выходе элемента i сэадёржки независимо от величины длительности действующейст1рокй всегда задерживаетс ртиосительно входного видеосигнала на длительность этой авйствуюшёй строки.. The number of pulses in the sequence corresponds to the number of capacitors of the ring accumulator of the delay element 1. This pulse sequence is controlled by a switch in delay element 1 that reads video signals from capacitors. We will receive a signal at the output of the output element i, regardless of the length of the active line, always delayed by the input video signal for the duration of this avowed line.

Формул а изобретении Устройство дл задержки телевизионного сигнала на длительность строки, содержащее элемент задержки и амплитудный селектор, входы которых подключены к выходу блока носител информации , отличающеес тем, что, с целью уменьшени помех при изменении длительности строки, введены последовательно соединенные умножитель частоты и генератор импульсов , выход которого подключен к управл ющему входу элемента задержки, выполненного в виде кольцевого накопител на конденсаторах, при этом %ход ум-ножител частоты подключен к выходу амплитудного селектора. Formula of the Invention A device for delaying a television signal for a line length, containing a delay element and an amplitude selector, whose inputs are connected to the output of a storage medium block, characterized in that, in order to reduce interference when the line length changes, a serially connected frequency multiplier and a pulse generator are introduced , the output of which is connected to the control input of the delay element, made in the form of an annular accumulator on capacitors, while the% stroke of the head-frequency knob is connected n to the output of the amplitude selector.
