histampl HistogramAmplitude
Definition:
The difference in value of the two most populated peaks in a histogram. This
parameter is useful for waveforms with two primary parameter values, such as
TTL voltages, where hampl would indicate the difference between the binary `1'
and `0' voltage values.
Description:
The values at the center (line dividing the population of peak in half) of the two
highest peaks are determined (see pks parameter description:). The value of the
leftmost of the two peaks is the histogram base (see hbase). While that of the
rightmost is the histogram top (see htop). The parameter is then calculated as:
hampl = htop - hbase
Example:
In this histogram, hampl is 152 mV - 150 mV = 2 mV.
