Abstract
Harmonic interference caused by limit cycles occurs in the resultant signals of filters for noise conversion as a consequence of limit cycles. A feedback loop is connected downstream of the actual filter and is used to effectively suppress the limit cycles. A feedback signal ythat is added to the output signal of the filter block is generated in the feedback loop. The invention can be implemented using both analog and digital technology.
