DFT Class

Member Function Documentation

Complex [] DSPLib.DFT.Execute

(

double[]

timeSeries

)

Execute the DFT.

Parameters

timeSeries

Returns

Complex[] FFT Result

double [] DSPLib.DFT.FrequencySpan

(

double

samplingFrequencyHz

)

Return the Frequency Array for the currently defined DFT.

Takes into account the total number of points and zero padding points that were defined.

Parameters

samplingFrequencyHz

Returns

void DSPLib.DFT.Initialize	(	UInt32	inputDataLength,
		UInt32	zeroPaddingLength = 0,
		bool	forceNoCache = false
	)

Pre-Initializes the DFT.

Must call first and this anytime the FFT setup changes.

Parameters

inputDataLength
zeroPaddingLength
forceNoCache	True will force the DFT to not use pre-calculated caching.

Property Documentation

bool DSPLib.DFT.IsUsingCached

getset

Read only Boolean property.

True meas the currently defined DFT is using cached memory to speed up calculations.
