fftcode_scope computes and displays spectrum of a signal stored in a Structure with Time format (Format used to save signals in Simulink Scope block and in To Workspace block). The signal must be sampled at fixed step. PSBFFT_SCOPE performs Fourier analysis of the NB_CYCLES last cycles of signal. The analyzed signal and a bar graph of the magnitudes of harmonic components are displayed . Harmonic magnitudes are displayed in percent of the fundamental component defined by FREQ_FUND and the magnitude of the fundamental value is written on the spectrum graph. For accurate results, use a sampling time giving an integer number of samples per period.
