Description
(54) МОДУЛЯТОР(54) MODULATOR
почти всегда, учитыва достаточную ре кость ,коротких черных элементов в факсимильном изображении, в состо нии , перебрасываетс в состо ние 1 только после коротко посылки ОV входного сигнала и об зательно возвращаетс в состо ние О после следукадей любой - короткой или некороткой - посылки О входного сигнала. Выходной сигнал триггера с его пр мого и инверсного выходов поступает на управл ющие входы формировател 3, выходной сигнал которого, следу закону изменени выходного сигнала триггера, измен етс преимущественно в пределах от нижней до средней частоты, переход после коротких посылок О входного сигнала на верхнюю частоту только на врем длительности следующей посылки 1 входного бинарного сигнала, после чего выходной ЧМ сиг .нал возвращаетс в прежние пределы измерени .almost always, taking into account the sufficient sharpness of the short black elements in the facsimile image, in the state, it is moved to state 1 only after shortly sending the OV of the input signal and necessarily returning to state O after following any - short or short - O input. signal. The trigger output signal from its forward and inverse outputs goes to the control inputs of the imaging unit 3, whose output, following the law of change in the trigger output signal, varies mainly from low to medium frequency, the transition after short bursts of the input signal to the upper frequency only for the duration of the next parcel 1 of the input binary signal, after which the output FM signal is returned to the previous measurement limits.
Предложенный модул тор выполн етс полностью на интегральных микроэлементах , содержит меньшее количест во функциональных узлов, что существенно упрощает и повышает его на-.The proposed modulator is performed completely on integral microelements, contains a smaller number of functional units, which significantly simplifies and enhances it.
дежность. Уменьшение ширины спектра выходного сигнала значительно облегчает качественную его передачу по каналам св зи.reliability Reducing the width of the output spectrum greatly facilitates its high-quality transmission over communication channels.
