Creating and Using Math Waveforms
Once you have acquired waveforms or taken measurements on waveforms, the
instrument can mathematically combine them to create a waveform that supports
your data-analysis task. For example, you might have a waveform obscured by
background noise. You can obtain a cleaner waveform by subtracting the
background noise from your original waveform (note that the background noise
you subtract must be identical to the noise in your signal). Or, you can integrate
a single waveform into an integral math waveform as shown below.

With spectral analysis you can analyze waveforms in the frequency domain. The
interface is similar to a dedicated spectrum analyzer, relieving you of the burden
of knowing the details of the underlying algorithms (see Figure 3--41).
