Device for reducing noise component in time-discrete signal, has primary provisioning unit for provisioning time-discrete signal with noise component, where secondary provisioning device provisions primary time-discrete reference signal

摘要

The device has a primary provisioning unit (110) for provisioning time-discrete signal with a noise component. A secondary provisioning device (120) provisions a primary time-discrete reference signal with a primary noise component and a secondary time-discrete reference with a secondary noise component. A subtraction unit (130) produces a differential signal from the two reference signals. The differential signal has a frequency component, induced by the noise components and a manipulation unit (140) for manipulating the time-discrete signal, so that the frequency component is reduced. An independent claim is also included for a method to reduce a noise component in a time-discrete signal.
