Q: For the signal shown in fig. below: i) Classify the signal ii) Give a mathematical expression for the sketched signal x(t). iii) Find TFS for the signal i.e. ao, an, b, and x(t)=2, + a, cos(not)+b, sin(noot) iv) Calculate the RMS value from the first three harmonic of the TFS (i.e. for n=0, 1, 2). v) Sketch the line (magnitude and phase) spectra for the first three harmonic of the TFS (i.e. for n= 0, 1, 2). -2 6 8
