4.6.4 Peak Detection
In the Data Display and the Spike Sorter display, you can select the option Peak Detection.
This option does only effect the display, not the data that is stored to the hard disk.
Peak Detection is a very important option. The massive amount of data points retrieved in
the range of the time axis, 200 ms in this case, that means 500 data points at a sampling rate
of 25 kHz, are reduced to a few pixels on the display, let us say to 100 pixels. That means,
five data points are reduced to one.
Without Peak Detection, only every fifth data point is actually plotted. The other four are
dropped. As you can imagine, it is likely that fast signals are overlooked or that you see peaks,
that are not actual present, but display artefacts.
