Abstract: 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.

Abstract: A controller and a method for controlling lamp drivers such as e.g. LED drivers for lamps having a fast response behavior such as e.g. LED lamps are proposed. They enable to substantially reduce or prevent a visible luminance flicker at such lamps when dimming the lamps with a conventional dimmer such as e.g. a phase cut dimmer. This can be achieved by switching off the lamp driver prematurely in such a way that a time jitter of a dimmer switching does not influence an on-time of the lamp driver. No bulky or expensive filters or capacitors are needed. Thus, a space-switch saving and/or inexpensive construction is enabled.
