Description

one

The invention relates to the field of pulsed technology.

A correction device is known comprising a corrected pulse amplifier with correction elements and an undocumented pulse summing amplifier connected in series with it, the second input of which is connected to the device input via a compensating circuit.

The purpose of the invention is to improve the quality of correction due to the compensation of natural oscillations in L, C, R corrective elements.

To do this, the linear modulator, the resonant system, the synchronous detector, the filter of the lower parts are included in the compensation circuit of the linear modulator, and the second input of the linear modulator is directly and the signals from the reference generator are fed to the second input of the synchronous detector.

The drawing shows a diagram of the device.

It works as follows.

When a source 1 of a corrected amplifier 2 receives a pulse signal from its source, a signal with distorted edges is released at the expense of the appearance of free oscillations in the L, C, R. elements of its load. In a single stage amplifier with simple voltage correction
