An amplitude-modulated oscillation E(t) = A(1 + mcos2Wt)coswt is supplied to the input of the oscillatory circuit with a high quality factor. When tuning the carrier frequency w, several resonances are observed. Indicate the resonant frequency values w. Determine the modulation depth m if it is known that the amplitude of forced oscillations in the circuit decreased by n = 4 times when the frequency w was adjusted from the value w0 to w0 + W + d (w0 is the natural frequency, d is the damping coefficient of the circuit).
