The oscillatory circuit is excited by a variable EMF, the frequency of which w differs from the natural frequency w0, and the detuning Dw = w0 - w is greater than the width of the resonance curve (|Dw| > d). Is it possible to “swing” oscillations in the circuit (figure) by periodically closing and opening switch K? At what switching frequency will the amplitude of oscillations in the circuit be maximum?
