Creating and Using Math Waveforms
Once you have acquired waveforms or taken measurements on waveforms, the
oscilloscope can mathematically combine them to create a waveform that
supports your data-analysis task. For example, you might have a waveform
clouded by background noise. You can obtain a cleaner waveform by subtracting
the background noise from your original waveform. Or, you can integrate a
single waveform into an integral math waveform as is shown below.

With spectral analysis you can analyze waveforms in the frequency domain. The
interface is similar to a dedicated spectrum analyzer, so you do not need to know
the details of the underlying algorithms (see Figure 3--38).
