Description

Devices are known that are made up of resistors connected in series and aKTiiBHOio resistance and allow to derive a derivative with changes in a constant voltage. However, from their to. It is not possible to control the change in the amp.shchudy of the alternating or brief) of his (pulsed) voltage noiiTfjpjiKnnerocn.

This problem is solved oniiebniaeMOc by the arrangement, from 1.Nichak p1, eee by the fact that the congresser shunt) is created by the active and active soybean juvenile1P1em.

The device diagram is shown in the npn / iarae.MOM drawing.

Capacity C is connected in series with matched 1E.1 R, njNHTn resistance :; R and S.Tuzhit d. 1 preserve the amplitude value of Is1pr: Ke / P1I for some time). It is sold, its life, and its capacity is determined by the capacitor and the counterpart RC driver. The valve D does not allow the following condition: Ramper frequency).

The test voltage U is applied to the terminals .4 and B. Irie. If there is a difference between it and the voltage L e on the capacitor, a charge current will flow through the resistance R.

If the magnitude and nature of the applied voltage U does not change, i.e., the subsequent voltage is equal to the previous one, it goes continuously or through the ravgp, 1e time intervals, then at terminals C and D the resistance R will be, respectively, singed or pulsed. with constant amplitude voltage U /.

Since then the following voltage will be used, U will become more and more often; , to her, the current, the passage through the resistance R, and the fall on it. Resistance to it will increase momentarily. Due to this, the voltage on capacitance C will increase and will correspond to the new

the value of the voltage U. The current is valid through the resistance R, the value of the voltage changed and ,; will decrease and become approximately equal to its previous one, its meaning.

If the next, and the amplitude becomes slightly longer, then the current through the resistance R, and hence the voltage drop across the letters, will instantaneously decrease. During this time, the voltage Uc on the capacitance C, as a result of leakage through RC, will also decrease and will again correspond to the value of the applied voltage U. The current through the resistance R will again return to approximately its previous value.

Thus, when the applied voltage U changes on resistance R, we get in the form of a short-term voltage change and an instantaneous sishal, the sign of which will correspond to the sign of the change in the applied voltage 0. The impulse received on the resistance R is applied to any video driver indicator or actuator.

The values of C, Re, and R are according to the time dependence of the applied voltage U, its periodicity and duration, as well as the required limits of accuracy of the solution of the problem and the nature of the latter, such as the need (| UG; | 1vappe for example U.
