WebDec 6, 2024 · The exponential Fourier series coefficients of a periodic function x (t) have only a discrete spectrum because the values of the coefficient 𝐶𝑛 exists only for discrete values of n. As the exponential Fourier series represents a complex spectrum, thus, it has both magnitude and phase spectra. WebOct 26, 2012 · It can also transform Fourier series into the frequency domain, as Fourier series is nothing but a simplified form of time domain periodic function. Fourier series. Periodic function => converts into a discrete exponential or sine and cosine function. Non-periodic function => not applicable. Fourier transform Webcos ( n x) = e i n x + e − i n x 2, sin ( n x) = e i n x − e i n x 2 i. From this, it follows that. a 0 = f 0, a n = f n + f − n, b n = i ( f n − f − n) EDIT: I have noticed that your formula in your question is wrong.
