Flipping causes a change in the polarity of the sensor
output signal and this can be used to separate the offset
signal from the measured signal. Essentially, the unknown
field in the ‘normal’ positive direction (plus the offset) is
measured in one half of the cycle, while the unknown field
in the ‘inverted’ negative direction (plus the offset) is
measured in the second half. This results in two different
outputs symmetrically positioned around the offset value.
After high pass filtering and rectification a single,
continuous value free of offset is output, smoothed by low
pass filtering. See Figs 19 and 20.
Offset compensation using flipping requires additional
external circuitry to recover the measured signal.
