Consider an amplifier of this output-input characteristics: Vo = C₁ V₁ + C₂ V2 + ...... Assume these inputs: fA(t) = a cos wдt fB(t) = b cos WBt Also assume: C₁ = 0 Cn for n > 3 Find the following: a. The level of the 2nd & 3rd harmonics relative to the fundamental if only one input is used. b. Repeat if the sum of two inputs is used. c. Repeat if the difference of two inputs is used. For b & c the amplitudes of both inputs are the same.
