FIELD: radio engineering, communication.SUBSTANCE: method of controlling attenuation in an oscillatory LC circuit is based on connecting an additional resistor ?<<r to the circuit between the earth and an inductance coil, where r is the active resistance of the coil, and introducing special initial conditions for generation of controlled oscillations. External emf is introduced into the circuit, the value of which is equal to the voltage across the resistor amplified k times without inversion and periodisation of the launch modes and the initial position. The required nature of attenuation is established and observed by controlling the equivalent resistance of the circuit r*=r-?(k-1); if r*>0 the process is attenuating, if r*=0 the process is not attenuating and if r*<0 the process is rising.EFFECT: establishing the required nature of attenuation in controlled oscillations.2 cl, 1 dwg |
