I have a system with an input signal x(t) = A·cos(w0t) and an output signal y(t) = B·cos(w0t) + C·cos(2w0t) + D·cos(3w0t). I want to get the transfer function H(f) = Y(f)/X(f). I have to calculate the Fourier Transform of x(t) and y(t), and as they are periodic functions, I thought about using the Dirac delta, but i don't know how to do it.
