Abstract (en)
[origin: EP0794686A2] A cable (11) interconnects the digital circuits of the microphone and its associated amplifier, the microphone digital circuit comprises a sound converter (1), two pre-amplifiers (V1,2), and two A/D converters (6) for a two-channel digital audio format. The two pre-amplifiers are coupled to the sound converter output and are linked each to one A/D converter, connected to a digital driver stage. The associated amplifier has a receiver and a signal processor, which generates a single-channel signal from the digital two-channel audio format, with the signal used for computing amplifying and filtering for the microphone.
