    Abstract: PROBLEM TO BE SOLVED: To provide a method for detecting AC voltage pulses of defined frequencies.
    SOLUTION: A detection circuit and a detection method for AC voltage phases of defined frequencies are disclosed. The detection circuit comprises: an analog/digital converter unit (A-D) for converting an input signal (1) into a sample value sequence (x(k)); at least one mix stage (4, 5, 12 and 21) for multiplying the sample value sequence (x(k)) by a mix frequency signal; at least one filter stage (13, 14, 22) for defining an allowable intermediate frequency band; and an evaluation unit which determines the presence/absence of AC voltage pulses using converted sample values. By this method, an input signal is transformed into a low-frequency signal by being multiplied by a mix frequency. The down-mixed signal can then be filtered and evaluated. The circuit is particularly suited for identifying charging unit signals of the telephone network.

    Abstract: The invention relates to a detection circuit and to a method for detecting alternating voltage pulses of a defined frequency. According to the invention, an input signal is firstly transformed into a low-frequency signal by multiplying this signal with a beat frequency. This signal that is reduced by mixing can then be filtered and evaluated. The circuit is particularly suited for identifying the charging unit signals of the telephone network.

    Abstract: A system and apparatus for establishing whether a received signal frame is an audio signal frame is disclosed. In one embodiment, the system includes a predetermined position in an audio signal frame containing a piece of secondary information for an audio characteristic of the audio data, with a selection device for selecting a succession of bits which is arranged at the predetermined position in the received signal frame. A decision-making device flags the received signal frame as an audio signal frame if the succession of bits represents the piece of secondary information.
