Determining and detecting noise products, noise sources, noise signals and/or noise situations in circuit arrangement involves using at least one of receiver units in circuit arrangement

摘要

The method involves determining and detecting noise products, noise sources, noise signals and/or noise situations using at least one of the receiver units in the circuit arrangement has. This receiver unit(s) is at least temporarily tuned to another frequency than the actual reception frequency of the circuit arrangement. AN Independent claim is also included for the following: a circuit for receiving and reproducing signals, especially audio signals and use of the circuit for determining and detecting noise products, noise sources, noise signals and/or noise situations.
