Run the FT_Simulator-File to execute the program!
Easy to use programm for a better understanding of the Fourier Transformation of Sinus and Rectangle functions.
Main Parameter: Sample frequency [Hz]
Signal Parameters: Amplitude, frequency [Hz], phase [°], offset, wave form.
Optional: Window function (Kaiser), Xlim (time, frequency domain), time and frequency domain (full or only positive), Zero Padding, FFT limitation (Chirp-z Transformation) and Sinc attentuation
Output: Signals in time (single, superimposed) and frequency domain as subplot figure and matlab data.
Enjoy!
