Circuit for reducing noise caused by at least one data bus signal in auto radios with bus connections, has subtraction device for subtracting at least one data bus signal from antenna signal

摘要

The noise reduction circuit has a first input for receiving an antenna signal including the noise signal from an antenna of the motor vehicle, a second input for receiving the at least one data bus signal from the data bus and a subtraction device (3) for subtracting the at least one data bus signal from the antenna signal. A signal shaping circuit (2) takes into account signal deformation with which the bus signal arrives at the antenna. AN Independent claim is also included for the following: (a) a method of reducing noise in auto radios with bus connections.
