Задача id13608

With free oscillations of a certain circuit, the amplitude drops by a factor of e in time t = 1 s. Assuming the quality factor of this circuit is large enough, find: a) detuning Dw1 (when taking the resonance curve), at which the power consumed by the circuit drops by half; b) detuning Dw2, at which the phase shift changes to p/4.
