Fourier Analysis

These are two M-files d-deDUfourier1d-deDt and d-deDUfourier2d-deDt The first is designed to demonstrate how triangular, rectangular, saw tooth, half wave and full wave rectified signals can be built from superposition of a predefined no of Fourier harmonic terms. It demonstrates how increasing...

PCSA is a frequency domain analysis technique that can be used to transform PSDs (as those in a spectrogram) to the form of a two-dimensional histogram with frequency-magnitude bins. PCSA can be used to examine the spectral characteristics of a long period of data. It summarizes magnitudes and...
