Even entry-level oscilloscopes today have simple math functions such as adding or subtracting two channels. But as [Arthur Pini] notes, more advanced scopes can now even do integration and ...
Modern digital oscilloscopes offer a host of analysis capabilities since they digitize and store input waveforms for analysis. Most oscilloscopes offer basic math operations such as addition, ...
Differentiation of algebraic and trigonometric expressions can be used for calculating rates of change, stationary points and their nature, or the gradient and equation of a tangent to a curve.
