Definition
The absolute value in A of the magnitude of the
analog signal (i.e., one-sided reading).
The peak-to-peak signal magnitude in A of the
analog signal.
The offset in A from the mid-point of the analog
peak-to-peak signal to the zero current point.
The number of electrical degrees between a transition
in channel A and the neighboring transition in channel B.
There are four states per cycle, each nominally 90 e.
The transitions are determined by where the analog
signal crosses the Zero point.
The deviation, in electrical degrees, of each state width
from its ideal value of 90 e.
The number of electrical degrees that an analog output
is greater than zero during one cycle. This value is
nominally 180 e or 1/2 cycle.
from its ideal value of 180 e.
