Description
Предлагаемое изобретение относитс к устройствам дл устранени вли ни помех при радиоприеме и состоит в воздействии на коэфициент усилени усилител в сторону его уменьшени при возникновении помехи.The present invention relates to devices for eliminating the effects of interference to radio reception and consists in influencing the gain of the amplifier in the direction of its reduction in the event of interference.
С целью напр жение на зажимах выходной цепи приемника подводитс к газосветной лампе, например, неоновой, вспыхивающей при увеличении напр жени на ее зажимах выше определенного уровн . Свет лампы воздействует на фотоэлемент, включенный в виде переменной утечки в цепь сетки одной из ламп усилител .For the purpose of the voltage at the terminals of the output circuit of the receiver, it is supplied to a gas-lighted lamp, for example, a neon lamp, flashing with an increase in the voltage at its terminals above a certain level. The light of the lamp affects the photocell, which is included as a variable leak in the grid circuit of one of the amplifier lamps.
Так как предлагаемое устройство безъинерционно , то вс кие помехи, дающиеSince the proposed device is inertia-free, all interferences that give
внезапные .выбросы амплитуд напр жени на выходе приемника, вызонут через неоновую лампу и фотоэлемент соогрзетствующее уменьшение сопротивлени в цепи сетки-катод той ллмпы, в которой включен фотоэлемент, и. соответственно, уменьшение усилени этой лампы.sudden voltage gains at the output of the receiver, through a neon lamp and a photocell, will cause a reduction in the resistance in the grid-cathode circuit of the lamp in which the photocell is turned on, and accordingly, reducing the gain of this lamp.
Предмет изобретени .The subject matter of the invention.
Устройство дл устранени вли ни помех при приеме; отличающеес пилючеиисм в цепь сетки одной из ломп усилител фотоэлемента, включенного в виде переменной утечки и освещаемого газосветнгй лампой, присоединенной к выходным зажимам приемника.A device for eliminating interference with reception; distinguishing pelucheiism in the grid circuit of one of the lomp photocell amplifier included in the form of a variable leak and illuminated by a gas luminaire connected to the output terminals of the receiver.
