Double Sided and Single Power Spectral Density using FFT: Next, the Power Spectral Density (PSD) of the Gaussian pulse is constructed using the FFT. PSD describes the power contained at each frequency component of the given signal. Double Sided power spectral density is plotted first, followed by single sided power spectral density plot Technically yes, you can obtain the power-spectral density (PSD) of a periodic signal by taking the squared-magnitude of its FFT. Note that if you are going to plot it on a logarithmic decibel scale, there is really no difference between 20*log10(abs(sf)) or 10*log10(abs(sf).^2). suppose that the length of frequency vector is 201, end/2=100.5 which is false the length should be an integer, use floor or ceil or fix, clear? 1 vysokE uCenI technickE v brnE brno university of technology fakulta elektrotechniky a komunikaCnIch technologiI Ustav radioelektroniky faculty of electrical engineering and communication department of radio electronics realizace ofdm kodEru pro potReby dvb-t realization of ofdm coder for dvb-t system diplomovA prAce master s thesis autor prAce author vedoucI prAce supervisor bc. This example shows how to obtain nonparametric power spectral density (PSD) estimates equivalent to the periodogram using fft. The examples show you how to properly scale the output of fft for even-length inputs, for normalized frequency and hertz, and for one- and two-sided PSD estimates.
