3. 1D or multidimensional processing?

Core Expertise Areas

Fourier Analysis

Fourier series: periodic signal decomposed into harmonics. Fourier transform: continuous signal to frequency domain representation. DTFT: discrete-time Fourier transform for discrete signals. DFT: discrete Fourier transform, finite length sequence, periodic in frequency. FFT: fast Fourier transform, O(N log N) algorithm for DFT computation.
