Abstract

The invention relates to amplifying devices operating in self-oscillation mode, with gyrotte-imfg-CE pulsed signal conversion. The aim of the invention is to improve reliability by reducing the number of relay elements. Multiband razvtyvayuyu; iy amplifier contains the first and second adders 1 and 2, integrator 3, relay elements 4, ... 4, input 5, output 6, source 7 of the reference voltage. The development amplifier operates in self-oscillation mode, which is maintained in a circuit formed by the first adder I, the integrator 3, one of the relay elements 4; and the second adder 2. Depending on the magnitude of the signal at input 5, the corresponding relay element is turned on. 2 Il. (L 4 Od 00 00 th

Relay elements, 4 have a characteristic with hysteresis. The number is ralis; x elements must be n-2 "B yes, we are very limited to three relay elements and we will assume that the intercept thresholds satisfy the condition

We assume that at the moment of time these output signals of the relay elements turn on, correspond to a positive level (FIG. 26) o Then a maximum amplitude pulse is generated at the output of the second adder 2. A (FIG. 2e). The output signal of the integrator 3 changes in the opposite direction (Fig. 2a) and leads to the sequential reorientation of the rening elements to the negative state (Fig; 2b-d) After that, the output signals of the second and third relay; 1 bshg, 2v. d) and the voltage to the reference reference is
