Multiple analog inputs are converted to respective multiple digital data
records by analog to digital converters. A switch inserts a pseudorandom "alignment"
code into each analog input at the beginning of conversion. After the analog to
digital conversion, this pseudorandom code is detected by correlator filters to
time align the plurality of digital data record with one another. The insertion
of the pseudorandom code allows multiple analog inputs to be digitally converted
in synchronization with one another. The disclosed logic controls its trigger timing
and operation method.
