Description

Предлагаемое изобретение касаетс  известного уже способа выделени  частот с применением дл  этой цели двух пьезоэлектрических пластинок и состоит в том, что обеим этим пьезоэлектрическим пластинкам фильтруемое напр жение сообщают в одной и той же ф зе, а в выходной цепи используют геометрическую разность токов, идущих через пластинки.The present invention relates to a method already known for allocating frequencies using two piezoelectric plates for this purpose, and consists in the fact that both of these piezoelectric plates are filtered voltage is reported in the same phase, and in the output circuit they use the geometric difference of the currents going through the plates .

На чертеже фиг. 1 изображает схему устройства дл  осуществлени  предлагаемого способа; фиг. 2 - схему видоизмененного устройства.In FIG. 1 shows a diagram of an apparatus for carrying out the proposed method; FIG. 2 is a diagram of a modified device.

Один из зажимов 6, 7 (фиг. 1), к которым подводитс  фильтруемое напр жение , присоединен к средней точке первичной обмотки 10 трансформатора 10,11 (в случае индуктивной св зи), а второй- к общему электроду 3 - двух пьезоэлектрических пластинок 1, 2. Два другихOne of the clamps 6, 7 (Fig. 1), to which the filtered voltage is applied, is connected to the middle point of the primary winding 10 of the transformer 10,11 (in the case of inductive coupling), and the second to the common electrode 3 - two piezoelectric plates 1 , 2. The other two

электрода 4 и 5 присоединены к первичной обмотке упом нутого трансформатора 10, 11, концы вторичной обмотки которого выведены к зажимам 8 и 9.electrodes 4 and 5 are connected to the primary winding of said transformer 10, 11, the ends of the secondary winding of which are connected to terminals 8 and 9.

В видоизмененном устройстве (фиг. 2- емкостна  св зь)зажим 7 присоедин етс  к общей точке двух, последовйтельно включенных с пластинами 1, 2 конденсаторов 12, 12, а выходна  цепь 8, 9 св зываетс  с устройством через конденсаторы 13, 13.In the modified device (Fig. 2 - capacitive coupling), the clamp 7 is connected to the common point of two capacitors 12, 12 connected in series with the plates 1, 2, and the output circuit 8, 9 is connected to the device through the capacitors 13, 13.
