Utility_Standardise: Signal Transformation

Generic Module Routines
The Process_Utility_Standardise(...) Process Routine
Example: Tests/Utilities/Standardise.c
- Parameter file: Standardise.par:
- Output

File name	UtStddise.[ch]

Description	This module uses the process EarObject's input signal to produces a standardised signal: sum(Si) = 0, sum(Si * Si)/N = 1. The method used uses the standard deviation and mean of the signal i.e sd = sum{(x - mean)^2 / n). The standardised values, Si = (X - mean) / sd.

Example parameter file format	This module has no parameters.

Test program directory	Tests/Utilities

Generic Module Routines

This module has no parameters so it does not need to be initialised, nor require any Set... functions.

The Process_Utility_Standardise(...) Process Routine

Syntax	BOOLN Process_Utility_Standardise(EarObjectPtr data);
