The PulseTrain2 component sends out a pulse every 60 samples. The output from
the PulseTrain2 is sent to the Trigger line on a latch. Therefore the output from the
latch is updated once every 60 samples. This generates an updated output that more
closely matches the data transfer rate of the motion tracker. The output can then be
sent to a head related transfer function (HRTF) coefficient generator (see "Using
the HTI3 with HRTF Filters" on page 17-15).

Another way to use the decimated signal would be to send it to a Serial Buffer
input. In this case the values are stored once every 60 samples. If you were using
this with OpenEx this would be the primary way to save the data set.
