A multi-sensor system includes a first analog sensor sub-system, a second
analog sensor sub-system, and a system for synchronizing the outputs of
the first and second analog sub-systems. Each analog sensor sub-system
includes a sensor that produces an analog output. Each sensor is coupled
to analog circuitry that processes the output from the sensor. The system
for synchronizing the outputs of the first and second analog sensor
sub-systems simultaneously inserts a marker into the outputs of the first
and second analog sensors. Then, the outputs of the analog circuitry of
the first and second analog sub-systems are synchronized based upon the
marker. The marker signal may be produced using a Barker sequence signal
generator.
