Package: com.neuromd.neurosdk
Spectrum power data channel. Heir to the base channel class BaseDoubleChannel. Spectrum power is calculated based on arrays of SpectrumChannel, channels specified in the constructor.
Includes the following fields:
|
SpectrumPowerChannel |
Constructor |
Options: channels[]:Spectrum channel array SpectrumChannel.
lowFrequency: The lower limit of the frequency for calculating the spectrum power in Hz.
highFrequency: The upper limit of the frequency of the spectrum power calculation in Hz.
name: An arbitrary text channel identifier.
windowDuration: Spectrum calculation window size in seconds.
overlapCoeff: Calculation window overlap factor. Values range from 0 to 1, where 0 is no overlap and 1 is maximum overlap |
|
SpectrumPowerChannel |
Constructor. Calculation window overlap ratio: 0.95. |
Options: channels[]:Spectrum channel array SpectrumChannel.
lowFrequency: The lower limit of the frequency for calculating the spectrum power in Hz.
highFrequency: The upper limit of the frequency of the spectrum power calculation in Hz.
name: An arbitrary text channel identifier.
windowDuration: Spectrum calculation window size in seconds. |
|
SpectrumPowerChannel |
Constructor. Spectrum calculation window size: 8 seconds. Calculation window overlap factor: 0.95. |
Options: channels[]:Spectrum channel array SpectrumChannel.
lowFrequency: The lower limit of the frequency for calculating the spectrum power in Hz.
highFrequency: The upper limit of the frequency of the spectrum power calculation in Hz.
name: An arbitrary text channel identifier. |

SetWindowDuration |
Method for setting the size of the spectrum calculation window in seconds. |
|
|
SetOverlappingCoefficient |
Method of setting the coefficient of overlap of the calculation window. Values range from 0 to 1, where 0 is no overlap and 1 is maximum overlap |
