The figure below is a squarelaw modulator the signal present

The figure below is a square-law modulator the signal presented to the nonlinear device is represented by v_2 = a_1v_1(t) + a_2v^2_1(t) where a_1 and a_2 are constants. v_1 (t) is the input voltage, and v_2 (t) is the output voltage. The input voltage is defined by v_1 (t) = A_c Cos(2 pi f_c t) + m(t) where m(t) is the message signal and A_c Cos(2 pi fct) is the carrier wave. Evaluate the output voltage v_2 (t). Specify the frequency response that the tuned must satisfy in order to generate an AM signal with f_c as the carrier.
