title: MATLAB 'spectrogram' params
body: <p>I am a beginner in MATLAB and I should perform a spectral analysis of an EEG signal drawing the graphs of power spectral density and spectrogram. My signal is <code>10</code> seconds long and a sampling frequency of <code>160 Hz</code>, a total of <code>1600 samples</code> and have some questions on how to find the parameters of the functions in MATLAB, including:</p>
  
  <pre><code>pwelch (x, window, noverlap, nfft, fs);
  
  spectrogram (x, window, noverlap, F, fs);
  </code></pre>
  
  <p>My question then is where to find values ​​for the parameters <code>window</code> and <code>noverlap</code> I do not know what they are for.</p>
