5-183. The coarse rate activity detector is a retriggerable

5-184. The timing comparator compares the identical

one-shot multivibrator that is held in conduction by bit

timing outputs of timing receiver No. 1 with those from

count 512 from the word counter in the coarse rate

timing receiver No. 2. When the timing signals are not

conversion circuits. When bit count 512 is missing, the

the same, the output of the comparator sets the timing

multivibrator's duty cycle expires and the coarse rate

error latch, which, in turn, applies a timing error signal to

error signal is applied to the composite error detector.
