Description

The invention relates to computing and can be used to perform multiplication and division operations.

A multiplier-separating device is known, which contains a modulator, the first input of which is connected to the source of the first input signal, and the output through a series-connected first AC amplifier and demodulator is connected to a reference voltage generator, -and the ring module p. The I / O of which is connected to the source of the second input signal, and the output through the second AC amplifier connected in series and the U-chain is connected to the zero potential bus.

A disadvantage of the known device is the need to use an additional external generator, which blew in 1C. AND: AND.

In the proposed device, in order to simplify the circuit, the output of the reference voltage generator is connected to the second input of the modulator 1 and the second input of the ring module.

Diagram of the device shown in the drawing.

The device contains a source of the first input signal 1, a modulator 2, a first AC amplifier 3, a demodulator 4, a reference voltage generator 5 whose frequency is used to modulate the input voltages, the source of the second input signal 6 , ring modulator 7, second AC amplifier 8 and 7 C-chain, consisting of capacitance 9 and resistor W.

where kg is the reduced converter factor (in the name of the division operation).

Thus, the magnitude of the voltage drop across capacitor 9 is proportional to the ratio of the two input voltage signals.

where ftg is the reduced transducer factor (in the multiplication operation mode).

The use of the modulator 7 at the input of the amplifiers of the bodies 8 provides a high input resistance for the signal from the input source 6.

To obtain a high input impedance from the input source 1. An AC amplifier 3 is used with a modulator 2, the carrier frequency of which is also supplied from the internal generator of the reference voltage 5.

When the external sources of input signals and 5 are connected, the first input signal controls the frequency of the internal oscillator 5. Moreover, a linear relationship is maintained between the input signal of source 1 and the reference frequency of generator 5. The signal from the source of input signal 6 is fed to the module The torus 7, the reference voltage to which is supplied from the generator 5. The signal from the modulator 7 through the linear amplifier 5 is fed to the / C-chain, with which the voltage is taken, proportional to the output voltage: and the ratio of the two input signals. High input impedance of the input source / is achieved through the use of

an input modulator 2, a reference voltage to which is supplied from the internal generator 5, 3 an alternating current 3 and a modulator 4.
