Error Analysis
¥A. The
absolute
error of a measurement is the difference between the ideal value x theory of a quantity (the measurement predicted by theory) and the
experimentally obtained value x measured .
Cr
Criteria of Accuracy: The relative
error is the error of each measurement divided by the theoretical value of that
measurement.
For parts of the experiment
where several measurements are taken at once (a power spectrum measurement on the spectrum
analyzer), you should
compare the error of each measurement against the maximum theoretical value in that set
of measurements (generally the theoretical amplitude of the first
harmonic).
