Problem Q

The graph above shows a periodic function of time. It is simply a sine curve, with all negative values truncated to zero.

  1. What is the period of this function?
  2. Write an equation which could be used to compute the Fourier coefficient A0. Do not evaluate the equation yet.
  3. Evaluate the equation to compute the value of A0.
  4. Write an equation which could be used to compute the Fourier coefficient A1. Do not evaluate the equation yet.
  5. Evaluate the equation to compute the value of A1.
