(..0 Addition and difference measurements
The measurement
of
the addition and difference is
it
function
repres
entin
g one waveform by adding two signals. The operation of
the addition (ADD) represent s the algebraic sum of the CHI and CH2
signals, and the operation of the difference
represents the
algebraic difference between the CHI and CH2 signals.
