    摘要: A radio receiver is provided having digital signal processing, a first and a second auxiliary signal derived from a received stereo multiplex signal, the first auxiliary signal being dependent upon the existence of signal components, whose frequency lies above the fundamental frequency range of the stereo multiplex signal, and the second auxiliary signal being dependent upon the symmetry of the sidebands of the stereo subcarrier. The first and the second auxiliary signal are combined to form an interference signal indicating the existence of interference. At least one control signal is derived from the interference signal to influence the audio signals acquired by decoding the stereo multiplex signal.

    摘要: In a circuit for digital processing of audio signals in a radio receiver, preferably in a car radio, the audio signals pass through a digital filter designed as a tone control, whose frequency response can be controlled with supplied coefficients, and a volume control, whose transmission factor can be controlled with supplied control signals. If the high and/or low frequencies are raised, the transmission factor of the filter at medium frequencies can be correspondingly lowered. Volume control compensates for the reduction. The volume control may contain a digital and an analog portion.
