FouSE-Fourier Series Expansion
by: Manuel J. Cabral S. Reis • 79
This app helps in the learning of Fourier series expansions. It has an easy-to-use, friendly interface, and can be viewed as a tool to help undergraduate students test and assess the Fourier series expansions on typical set of signals, such as:
-- |\sin| (full wave rectified);
-- Half sin (half wave rectified);
-- Parabolic (t^2).
Some of its main characteristics include the ability for the students to control the total approximation error and the number of terms/harmonics used in the expansion.
