%% Mean-Square Spectrum of Sinusoids % Create a signal consisting of two sinusoids in additive noise. Fs = 32e3; t = 0:1/Fs:1-1/Fs; x = cos(2*pi*t*1.24e3)+cos(2*pi*t*10e3)+randn(size(t)); %% % Compute the one-sided PSD estimate of the signal. Use the result to % construct a |dspdata| object. Plot the mean-square spectrum. P = periodogram(x,[],[],Fs); Hmss = dspdata.msspectrum(P,'Fs',Fs,'spectrumtype','onesided'); plot(Hmss)
