Frequency-Domain Analysis with DFTs

Addresses the fundamental concepts of frequency spectrum analysis using discrete Fourier transforms. Topics range from the discretization of measured physical phenomenon to the interpretation of periodogram spectral content in terms of the Fourier basis sinusoids. The text also discusses peculiarities that arise due to discretization, such as leakage and aliasing.

Abordeaza conceptele fundamentale ale analizei spectrului de frecventa utilizand transformate Fourier discrete. Subiectele variaza de la discretizarea fenomenului fizic masurat la interpretarea continutului spectral al periodogramei in termenii sinusoizilor bazei Fourier.
