Class: TSLNoiseStats

Contents 1 Syntax 1.1 Delphi: 1.2 C++ Builder: 2 Summary 3 Description

Syntax

Delphi:

property WindowThreshold : Real read FWindowThresh write SetWindowThresh default 0;

C++ Builder:

__property double WindowThreshold = { read=FWindowThresh, write=SetWindowThresh, default=0 };

Summary

Threshold for bins with (frequency-domain) window magnitudes.

Description

Prior to the initial FFT, a (time-domain) windowing function is applied to the input data stream (see property WindowType). After the initial FFT, in order to calculate SNR and other results, only bins with (frequency-domain) window magnitudes larger than WindowThreshold are included in calculations. Note WindowThreshold is set automatically when property WindowType is changed. The automatically set values will suffice for most clients.
