Description
Известно устройство дл симметпирор, амплитуд токоз, протекающих по обмот1 ам приемного реле при двух гастотпом To:ia,nb iOi телеграфировании, в котором прин тые двухчастотныо телеграфные л--:сылки после детектировани действу от lui обмотки пол ризова1и ого реле, включенные по дифференциально схеме, между которыми полключено симметрирующее переменное сопротивление, регулируемое так, чтобы получить минимальную ве,Ч|;чину искажении, принимаемых сигналов.A device is known for symmetrical, amplitudes of currents flowing along the windings of the receiving relay with two To: ia, nb iOi cabling, in which the received two-frequency telegraph L -: links after the detection of the polarizing relay winding from lui, switched on by differential circuit, between which the polarizing variable resistance is switched on, adjustable so as to obtain the minimum be, H |; the rank of distortion of the received signals.
Недостаток подобпого устройства состоит в том, что дл выравнивани амплитуд токов, протекающих по обмоткам приемного пoл p iзcванного реле, приходитс производить многократную регулировку переменного сопротивлени , так как любое измс1;ение полол ени его ползунка измен ет степень щунтировани обмоток i5e:ie, что приводит к возникновению дополнительной асииметрин.The disadvantage of such a device is that in order to equalize the amplitudes of the currents flowing through the windings of the receiving field of the idle relay, it is necessary to make multiple adjustments of the variable resistance, since any change in the value of its slider changes the degree of shunting of the windings i5e: i.e. to the occurrence of additional asiimethrin.
В описываемом устройстве этот недостаток устранен включен 1С1/1 параллельно обмоткам приемного реле высокоомного конту 1а, содержащего нелинейное сопротивление, чем достигаетс создание napaj;лельного пути только дл тока посылки, имеющей большую амплитуду.In the described device, this disadvantage is eliminated by switching on 1C1 / 1 parallel to the windings of the receiving relay of the high-resistance circuit 1a, containing non-linear resistance, which achieves the creation of a napolej path only for the current of the parcel having a large amplitude.
Устройство содержит два полосовых фильтра 1 и 2 (см- схему}, включенных параллельно и настроенных на соответствующую тональную частоту. На выходе фильтров включены согласующие трансформаторы 3, 4, нагруженные на мастиковые схемь 5, 6, служащие дл гыпр млени принимае.мых сигналов. Дл фильтрации выпр мленныхThe device contains two bandpass filters 1 and 2 (see the circuit diagram} connected in parallel and tuned to the appropriate tone frequency. The output of the filters includes matching transformers 3, 4 loaded on a mastic circuit 5, 6, which serve to generate the received signals. For filtering rectified
