The Continuous Time Fourier Series is a good analysis tool for systems with periodicexcitation. Understanding properties of Fourier series makes the work simple in calculating the Fourier series coefficients in the case when signals modified by some basic operations. Graphical representation of a periodic signal in frequency domain represents Complex Fourier Spectrum.
