A PHASE relation familiar to students of applied mathematics exists between a simple harmonic oscillation and its derivative. Similar relations exist between exponential functions and their ...

Often the time derivative of a measured variable is of as much interest as the variable itself. For a growing population of biological cells, for example, the population’s growth rate is typically ...

Oscilloscopes are the workhorse instruments for time domain measurements. Most current digital oscilloscopes include about twenty-five built in measurement parameters as a standard complement. Adding ...
