MATLAB Code for Fourier Series Handling (with FFT)
The MATLAB FFT/IFFT functions are good but not so easy to use for real periodic signal:
- the ordering of the frequency vector is confusing due to the negative frequencies (spectrums are symmetric)
- the coefficients are not scaled as in a Fourier series due to the definition of the DFT
The provided MATLAB functions offer different functionalities around Fourier series:
- get time and frequency vector
- wrappers around the MATLAB FFT/IFFT functions that scale periodic signals as Fourier series coefficients
- many signals can be processed at the same time (matrices)
The following functions are offered for signal generation:
- generate spectrum of arbitrary PWM periodic signals directly in the frequency domain
- generate PWM signals with a finite/infinite slew rate
- generate DC and AC sinusoidal signals
Additionally, several transformations can be applied to frequency domain signals:
- apply low-pass filters (e.g., first-order, second-order)
- apply simple transformations (eg., delay, phase shift, AC coupling)
Examples
Compatibility
- Tested with MATLAB R2018b and R2021b.
- No toolboxes are required.
- Compatibility with GNU Octave not tested but probably easy to achieve.
