Oscilloscope Reference Measurements on envelope waveforms
A and B are numbers between 0.0 and RecordLength –1.0
If A and B are integers, then:
where s is the sample interval.
Similarly,
W(t) is the sampled waveform
Ŵ(t) is the continuous function obtained by linear interpolation of W(t)
A and B are numbers between 0.0 and RecordLength –1.0
If A and B are integers, then:
where
s is the sample interval.
Measurements on envelope waveforms
Time measurements on envelope waveforms must be treated differently from time measurements on other
wav
eforms, because envelope waveforms contain so many apparent crossings. Unless otherwise noted,
envelope waveforms use either the minima or the maxima (but not both) , determined in the following
manner:
1. Step through the waveform from Start to End until the sample min and max pair do not straddle MidRef.
