    摘要: An IR receiver having a decision logic circuit for activating or deactivating a squelch. Activation or deactivation of the squelch is effected in dependence on a mean value of the frequency, a variance of the receiver intermediate frequency, a mean value of the audio amplitude, a variance of the audio amplitude and/or a signal strength of the receiver intermediate circuit frequency.

    摘要: The invention is directed to a method for encoding data of a data signal by a periodic synchronous signal having at least two signal levels in a baseband signal. To provide a possibility by which the data of the synchronous signal can be encoded and decoded again in a simple and economical manner without having to employ the expensive hardware used in known methods, it is proposed, according to the invention, that the baseband signal is generated by combining the data signal and the synchronous signal, this combining step being carried out in such a way that, depending on the signal level of the synchronous signal, the signal level of the baseband signal lies in an associated level range independent from the data signal. The invention is also directed to a corresponding method for decoding a baseband signal and corresponding circuit arrangements. The method is preferably used for encoding and decoding audio signals.

    摘要: A multiplex transmission device for multiple-channel signals, in particular multiple-channel audio signals, has a plurality of input channels, each of which receives an input signal, a multiplexer, the input channels being connected with the inputs of the multiplexer, and with an output channel which is connected to the output of the multiplexer for sending an output signal which is multiplexed from the input signals. A control element is connected in each input channel for controlling the amplitude of the respective input signal and a regulating device is provided for controlling the control elements. A special feature of the device consists in that the regulating device uses the output signal of the multiplexer as a regulating variable.
