    摘要: A loop filter includes an input terminal, an output terminal, and a control terminal for a selection signal. At least one low pass filter is disposed between that input terminal and that output terminal. The loop filter is adapted to select a configuration out of a first configuration and at least one second configuration in response to the selection signal. In the first configuration, the loop filter comprises a non-integrating transfer characteristic in operation. In the second configuration, the loop filter comprises an integrating signal transfer characteristic in operation.

    摘要: A frequency-dividing circuit arrangement is disclosed that includes a divider chain having a plurality of frequency divider stages. The frequency dividers can be changed over between the division ratios 2 and 3. At least that frequency divider that is arranged on the output side of the divider chain has an additional through-switching input that makes it possible to switch through the input signal to the output of the divider stage without influencing the delay-time effects of the divider stage. The advantages of a cascaded 2/3 divider chain, such as a high cut-off frequency, a simple design and the ability to arbitrarily expand, are thus achieved without accepting a lower limit of the range of possible division values.
