Definition of Fourier Series and Typical Examples Baron Jean Baptiste Joseph Fourier \(\left( 1768-1830 \right) \) introduced the idea that any periodic function can be represented by a series of sines and cosines which are harmonically related. Prof. Gabriel Popescu Fourier Optics 1.3. Example Problems • Express as convolutions with -functions. • Prove the sampling property of the delta function. • Solve the integrals.

Many of the ordinary properties of the Fourier transform are valid unchanged even for the discrete Fourier transform. This means for example that the DFT is linear, scaling affects both the frequency and the amplitude, and a spatial displacement only affects the phase of the transform and so on.
