A square wave is given by f(x)=0, -A 5x<0 f(x)= h, 05x<T, Express this as a Fourier series. Plot the first five terms of the series. Use whatever software you like for plotting, it can be Wolfram Alpha, or Matlab, etc. Then sum them together. Suppose you have a circuit that cannot pass high frequenies. What will happen to a perfect squarewave used as input this circuit, i.e. what will the output look like?
