The “Magnitude of DFT of Original Sequence” refers to the absolute values or magnitudes of the complex numbers obtained from the Discrete Fourier Transform (DFT) of the original sequence.
In the provided code, it is computed using the abs(XF) expression, where XF represents the DFT of the original sequence x. The result is then plotted using the stem(n, abs(XF)) function.
This magnitude spectrum provides information about the amplitude or strength of each frequency component present in the original sequence. It helps visualize how different frequencies contribute to the overall signal.
