6.2.3.2 Azimuth Signal
The Vibrex unit routes azimuth (frequency or tachometer) signals from
one of two channels by a multiplexer. These signals then go to a pulse
detector, a threshold-adaptive detector that translates azimuth pickup
input signals (from the magnetic pickup or photocell) to digital logic
levels.
The detector picks up peak pulse levels as low as 0.5V. The digital signal
then goes to the microprocessor TPU for calculating periods and phase
references.
