Description

Известны устройства групп источников импульсного генератора электронной АТС, основанные «а использован ии кольцевой схемы или делител  частоты в сочетании с последовательно включенными триггерами , схемами совпадени , формирующими триггерами и усилител ми.The devices of the groups of sources of the pulse generator of electronic PBX are known, based on the use of a ring circuit or a frequency divider in combination with series-connected triggers, coincidence circuits, shaping triggers and amplifiers.

Предложенный генератор сер й имлульсов отличаетс  от известных тем, что формирование импульсов осуществлено в многофазном формирователе, а на вход каждого усилител  поданы импульсы от общего триггера, запирающие усилитель на врем  защитного интервала. Этим достигаетс  улучщение формы импульсов и уменьшеиие объема генераторного оборудовани .The proposed gray emulsion generator differs from the known ones in that the pulse formation is carried out in a multiphase shaper, and at the input of each amplifier pulses from a common trigger are applied, locking the amplifier for the time of the guard interval. This is achieved by improving the pulse shape and reducing the volume of the generator equipment.

Предложенный генератор может быть использован на электронной АТС с импульсно-временным способов разделени  каналов « на механо-электронных АТС, примен ющих импульсно-временной принцип действи  управл ющих устройств.The proposed generator can be used in an electronic PBX with pulse-time channel separation methods into mechanical-electronic PBXs using the pulse-time principle of operation of control devices.

На фиг. 1 показана блок-.схема предложенного генератора с многофазным формирователем серий импульсов, выполненным по кольцевой схеме и временна  диаграмма его работы; на фиг. 2 - бло-к-схема генератора с многофазным фор.мирователем серии импульсов, выполненным с делителем частоты, и временна  диаграмма его работы.FIG. 1 shows a block diagram of the proposed generator with a multiphase pulse shaper formed according to a ring circuit and a timing diagram of its operation; in fig. 2 is a block diagram of a generator with a multiphase pulse series generator made with a frequency divider, and a time diagram of its operation.

Синхронизирующие импульсы запускают многофазный формирователь (триггеры J, 2 ц 3} серий импульсов, который вырабатывает пр моугольные импульсы с частотой следовани  в л раз меньщей, чем частота следовани  запускающих импульсов, и сдвинутых по времени (п - число триггеров в многофазном формирователе).The synchronizing pulses trigger a multi-phase driver (triggers J, 2 n 3} of a series of pulses, which produces rectangular pulses with a frequency that is l times smaller than the frequency of the pulse, and shifted in time (n is the number of triggers in the multi-phase driver).
