SIGNAL PROCESSING ARRANGEMENT
A signal processing arrangement comprises a series of latches (XDL, L1, L2) arranged as a clocked delay line (CDL) having a data input and a data output that are coupled to each other so as to form an inverting loop. An enable circuit (ACDL) allows or prevents a latch (L2) in the series of latches f...

Zusammenfassung: | A signal processing arrangement comprises a series of latches (XDL, L1, L2) arranged as a clocked delay line (CDL) having a data input and a data output that are coupled to each other so as to form an inverting loop. An enable circuit (ACDL) allows or prevents a latch (L2) in the series of latches from changing state depending on whether, one clock cycle ago, the latch concerned received a given binary value or the inverse of that given binary 5 value, respectively, from the preceding latch (L1) in the series of latches. Such a circuit configuration allows a low-cost frequency division by an odd number with relatively small duty cycle errors. |
