Abstract (en)
[origin: EP2009955A2] A signal processing unit (10) supplies the output signal to a noise reduction unit (11) through a channel (K1). The output signal is supplied to a level limiter (12) through a channel (K2), to limit the output signal level to predetermined degree. The output signals from the noise reduction unit and level limiter are added by an adder (13) to output an overall output signal (SG). An independent claim is also included for interference noise reduction method.
