【實用教育app】FouSE-Fourier Series Expansion|最夯免費app-綠色工廠好玩App

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:

-- Sawtooth;

-- |\sin| (full wave rectified);

-- Half sin (half wave rectified);

-- Square;

-- Triangle;

-- 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.
