Geopsy: Decimate amplitude
Revision as of 16:25, 10 March 2010 by Clotaire Michel (talk | contribs)
Decimate amplitude, reached from the Waveform menu, lower the quality of signals in the active signal viewer.
By clicking on Decimate amplitude, a pop-up window appears with the following options:
- Absolute maximum number of steps is the number of amplitude bins that should be used for positive values. Ex: a value of 1 leads to three amplitude bins: -1, 0 and 1 (1-bit data).
- Amplitude reference allows to define the value of largest amplitude bin. It can be set to:
- Value, i.e. a specified value, e.g. 1 Volt to simulate a 2V peak-to-peak digitization.
- Maximum to set it to the maximum value of the active signals.
Decimate amplitude can be used to test the robustness of a signal processing to the quality of the recordings. It allows to simulate recordings done by low quality digitizers. Decimate amplitude modifies the temporary signals in the active viewer.
