Hello, I wonder why the following code showing the error (i.e. Undefined variable "dsp" or class "dsp.SpectrumAnalyzer".)?
fs = 100;t = (0:1/fs:100)'; fc = 10; x = sin(2*pi*t); ydouble = ammod(x,fc,fs);ysingle = ssbmod(x,fc,fs); sa = dsp.SpectrumAnalyzer('SampleRate',fs,'PlotAsTwoSidedSpectrum',false,'YLimits',[-60 40]); step(sa,ydouble)
Regards

You might not have the DSP System Toolbox installed.
Try using pwelch() or periodogram()
