Signals

A signal is a sequence of samples each having a value. The signal's values can be accessed in a formula by adding the signal to the formula. It will be displayed as a box with the name of the signal.

Implicitly each signal also has a time stamp for each sample. Some operations like the Integral use the time stamps to react to the passing of time. To explicitly access the time in a formula use the Master() function.

Examples:

• Delta(signal) calculates the difference of consecutive signal values.

• Delta(Master()) calculates the difference of consecutive signal time stamps, e.g. Delta(Master())+0*signal.
