8. Given Vs (t) = [6cos2x1Kt+ 5cos2x2Kt + 4cos 275Kt] V as the input of the system below. A 8V DC signal is added toVs(t) using a summing circuit and this DC offset signal is the input to an analog multiplier that multiplies the signal and a high frequency sinusoidal signal cos(2x100K t) V. Plot the power spectrum of Vour (t) in dBw. Vs (t) Σ 8V Vout (t) Cos (2n100Kt) V
