The ‘flipper’ circuit (Block 1) generates the flipping current,
with a flipping frequency determined by R16 and C3,
about 1 kHz in this case. As previously stated, the
frequency is not critical and can be selected to minimize
the need for post filtering and/or to provide the required
response time.
The flipping frequency drives the synchronous rectifier as
well as the flipping coil. As the signal passes from high to
low, C4/R17 together produce a pulse that switches TR2
on. This charges C6 and a short positive pulse is passed
to the flipping coil. For a low-to-high signal transition,

C5/R18 forces TR1 to conduct, making C6 discharge and
providing a negative pulse through to coil. An oscillograph
of the current through the flipping coil is shown in Fig.27c,
with a duration of about 10 s and maximum current
amplitude of around 0.7 A. The other diagrams show the
responses of offset compensation (Fig.27b), and
measuring magnetic pulses (Fig.27a).
