摘要： A transmitter for a wireless audio transmission system has at least one analogue/digital conversion unit for the analogue/digital conversion of the analogue audio signals to be transmitted, at least one digital signal processing unit with compressing/encoding means for compressing and encoding the digitised signals to be transmitted, a digital/analogue conversion unit for the digital/analogue conversion of the digital output signals from the digital signal processing unit into analogue signals, and a transmission unit for wirelessly transmitting the output signals from the analogue/digital conversion unit. Also disclosed is a receiver for a wireless audio transmission system having a reception unit for receiving wirelessly transmitted analogue H.F. signals, an intermediate frequency unit for mixing the H.F. signals into intermediate frequency signals, at least one analogue/digital conversion unit for the analogue/digital conversion of the wirelessly received signals, at least one digital signal processing unit with expanding/decoding means for expanding and decoding the signals digitised by the at least one analogue/digital conversion unit, and at least one digital/analogue conversion unit for converting the digital output signals from the digital signal processing unit into analogue signals.

摘要： The aim of the invention is to create a detection device that is able to determine whether a microphone or audio signal processing apparatus which is connected thereto operates in an analog or digital manner, an analog or digital terminal being selected according to said determination. Said aim is achieved by a detection device comprising a sensing unit (6), a determination unit (5), and a selection unit (4). The sensing unit (6) senses an external signal that is fed to the detection device and forwards said signal to the determination unit (5). The determination unit (5) determines whether the sensed external signal has been transmitted by an analog or digital audio signal processing apparatus and transmits a corresponding determination signal to the selection unit (4). The selection unit (4) subsequently selects an analog or digital terminal according to the determination signal.
