Sets the Signal Generator to output (i.e. track) an input signal. The
frequency output is saved in b.
This example can take a square wave input (or anything else for that matter) and produce a tracking generator,
outputting a sine wave of the fundamental frequency. This could be useful for waveform clean up, transfer
functions, making a VCO, etc.
19.2.1 Maths Equations Operators and Functions
The Maths equation editor supports the + - * / ^ ( ) operators.
The : operator is a special operator that is used to separate the two values that are used by some processes.
It supports the following functions, which can be used to construct each Maths equation using the operators.
Each operator and function acts on the sample set point by point.
