Inventively refers to analog computing technology and can be used in particular when constructing a measurement device (5st, for example, watt-meter of logometers and so on; nd.

A multiscale device is known, containing amplifiers, KEYS and rectifier ll,

The disadvantage of this device is the relative complexity and nevyvuokok accuracy

The closest to the one proposed in the copying device, which is a quadrupole, the Key modulator, whose information input is the first unit of the device, the phase modulator, the carbon pulse generator, the output of which is connected to the key inputs of the key modulator and you are two-phase-sensing, and two dividing RC jenHjs are one of which, including between the way of the kvassfetor and the input of the phase-sensing pin of the rectifier, and the other - between the key mover of the torus and the quadrant, When in use, the free You are a VOC of this resistor RS-chdepi potssoetsinen to second inputs jfCTpoftcTsaf.

Lack of this device ow -

5 uTh: the external voltage of the capacitor of the second separating filament, which makes it difficult to do i device imperatively with modern requirements

10 tonnes, the complexity of the design reduces the depletion of the device.

The purpose of the invention is to increase the reliability and expand the dynamic range of the input sigals,

The drawing shows the functional diagram of the multiplying device. The multiplying device contains a Key Modulator 1, a Quadrator 2, a generator 3 rectangular imputs, a pha-sensitive rectifier 4, a split NS 5 and 6, a block 7 of subtractions. Capacitors 8 and 9, resistors 1O and 11 and bus 1 2 zero potential. The output of Generator 3 is connected to the control inputs of the key modulator 1 and the phase-sensitive rectifiers of bodies 4. The information input of the modulator 1 is the first input of the device, and the second output of the 1O resistor of the first NS 5 is connected to the second input of the device. The first input of block 7 is connected to the output of quad 2, and the second is connected to the upper side of the device, and the output is connected to the second plate of the concentrator 8 of the second RC circuit 6, the device operates as follows. The input to the x-mode lff 1, controlled by rectangular pulses with a duty cycle fi 2 from generator 3, receives a voltage J, which is converted into a stream of positive and negative polarity pulses of equal duration and amplitude. At the output of the dividing RC circuit 5, a total voltage is formed from the output of the modulator 1 and the second ground voltage
