Properties

Published

• Normalization - The normalization type for the FFT operation.

From TSLFourierBase

Properties

Published

• WindowType - Windowing function to be applied on the signal prior performing FFT.
• NumberTerms - Specifies the number of Cosine sum window function terms.
• Order - The order of the FFT.
• SamplingWindowStep - Step in samples when the next FFT will be applied.
• Synchronize - Specifies if the OnFrequencyResult event will be synchronized with the main thread.

Pins

• FrequencyOutputPin - Single Sample Real(double) data Highest Frequency Output Pin.

Events

• OnFrequencyResult - Occurs when highest amplitude frequency is detected.

From TSLFourierBaseComponent

Properties

Published

• Alpha - Adjustable parameter associated with some of the windowing equations.
• IgnoreDC - Ignores the DC component.

Pins

• InputPin - The Real(double) or Complex input pin of the FFT.
• OutputPin - The Complex output pin of the FFT.
• SpectrumOutputPin - The Real(double) spectrum output pin.
