Method Detail

setDataGain

public void setDataGain(double[] gain)

getDataGain

public double getDataGain(int chan)

Description copied from class: PamDataBlock

Return the gain applied to any data created into this datablock.

Example 1: The amplifier module will just return it's gain

Example 2: The FFT module will return the loss due to windowing the data.

To convert to dB use 20*log10(Math.abs(getDataGain()));

Overrides:

getDataGain in class PamDataBlock<RawDataUnit>

Parameters:

chan - channel number

Returns:

gain as a factor (to allow for negative gains)
