Suppose that you now have a stereo audio signal with unbalanced left and right channels, where the left channel has a maximum output of 500 mVpp and the right channel has amaximum output of 200 mVpp. You want to produce a 20 Vpp output that is thebalanced and inverted sum of these two channels. In other words, the amount ofamplification done to each channel needs to be different to compensate for theunbalanced signal amplitudes. Design and build a circuit that will perform thisweighted sum amplification.
