Unformatted text preview: Let be a pulse train with period that is defined over one period as We compute coefficients of the Fourier series for this signal as follows, The special case is computed separately, , we compute the Fourier series Note that the coefficients are real‐valued. To approximate The question now is how to choose , the number of terms in the finite Fourier series? We choose enough terms so that the frequency of all complex exponentials is less than radians/sec. That is, we choose so that for all integers and thus will increase as increases. In other words, for the same maximum frequency we will use ma...
