A single tone signal m(t) = Am cos 2nfmt is used to generate the modulated signal where a is a constant, 0 sas1. (a) By representing the modulated signal in the form $(t) = A,m, (t) cos 2n fet + A,mz(t) sin 2nf.t, determine the choice of the parameter a required for the modulated signal to be %3D classified as QAM, SSB, or VSB. (b) The modulated signal (t), plus the carrier Acos 2nfet, is passed through an envelope detector. What is the output of the envelope detector? Determine the distortion produced by the quadrature component m2(t). (c) What is the value of constant a for which this distortion reaches its worst possible condition?
