Rectangle impulse with height Um and width T is given. For calculating spectra DFT was used with step T=T/8 and K = 16 samples. Um = = 12 V T = 5 s. Please draw what could calculated spectra look like (indicate at which frequencies the spectral values were calculated) Explain what will happen/change if you take K = 32 samples at the same T value Notepad or matlab could be used here.
