pulse that identifies the first data bit of each code word.
(1) U3A is used to restore the NRZ code word
from U4-3. U3-1 and 2 will be delayed one clock period and
g. NRZ to Biphase Converter. The NRZ code output
bit period by operation of the D flip-flop U3A.
(2) U3B provides synchronization of the EOW
from U3A-1, or its complement from U3A-2providesthe input
pulse from U4-13. This pulse is also delayed one clock period
signal to U1B-8. The exclusive OR operation of U1B creates
by U3B, and the output from U3B-13 will be a positive
the biphase code word from the NRZ input and the clock
signal UIB-9.
