In an AM/DSB-LC modulator, the carrier signal is c(t) = 4 cos(6π107 t) and th m(t) = cos(7000πt). The signal c (t) +m (t) is applied to the input of a characteristics given by i (t) = a₁vi (t) + a₂ v₁² (t) where a₁ and a₂ are positi of the nonlinear device at a resistance R is passed through an ideal band pass filte frequency and 10500 Hz bandwidth to produce the modulated signal. If you know of the AM wave is half of the carrier power, find the ratio a₁/a2.

Question
> In an AM/DSB-LC modulator, the carrier signal is c(t) = 4 cos (6107 t) and the modulating signal is m(t) = cos(7000πt). The signal c (t) +m (t) is applied to the input of a nonlinear device whose characteristics given by i (t) = a₁v₁ (t) + a₂ v² (t) where a₁ and a₂ are positive constants. The output of the nonlinear device at a resistance R is passed through an ideal band pass filter with 3*107 Hz center frequency and 10500 Hz bandwidth to produce the modulated signal. If you know that the sideband power of the AM wave is half of the carrier power, find the ratio a₁/a2.
