Switching circuit arrangement for receiver e.g. microphone, has analysis module to generate characteristic data sequences based on analysis signal and indication unit for indicating unwanted data sequences

摘要

The switching circuit arrangement (20) has an input module (21) which receives information signal from a transfer module (13). The analysis signal is generated based on information signal. An analysis module (22) is set to generate real-time characteristic data sequences based on the analysis signal. A comparison module (24) is provided to compare the generated data sequences with preset data sequences stored in a reference memory unit (25). The analysis module is connected with an individual indication unit (28) which is set for indicating unwanted data sequences.
