  • CIRCUIT AND METHOD FOR DETECTING AC VOLTAGE PULSES
    Publication number: 20060210055
    Abstract: A detection circuit and method for detecting AC voltage pulses at a defined frequency relate to first transforming an input signal to a low-frequency signal by multiplying the input signal by a mixing frequency. This down-mixed signal can then be filtered and evaluated. The circuit is particularly suitable for identifying charge unit signals in the telephone network.

  • Suppression of disturbances, caused by burst-like changes of the data rate, during synchronous radio transmission
    Publication number: 20060002295
    Abstract: In a receiving device (1) and method for reception of data packets by radio, having a memory (4), values derived from the values of received data packets are entered and values are emitted for further processing from it. The device comprises a regulating unit (6) for regulating the filling level of the memory (4) at a nominal filling level, with the regulating unit (6) controlling the number of values entered in the memory (4) per received data packet as a function of the filling level.
