You are given the waveform: x(t) = -10 + 3 cos(2130t + 40°) — 4 sin(2160t + 10°) + 2 sin(21120t) – 3 cos(21120t) = - a) What is the fundamental frequency w. (in rad/sec), the fundamental period T (in s), and the fundamental frequency fo (in Hz). b) Determine the an values for the waveform.
c) Plot the Fourier transform magnitude |X(W) and ZX(w) on the graphs below. Make sure that all of your axes are properly labeled. |XW| 3 ZXW) w
