Frequency modulated (FM) radio band audio interference pre-compliance test

The FM band radio is one of the most common receivers found in todaypsilas automobile and is considered to be an important factor in consumerspsila ratings of vehicle quality and craftsmanship. As automotive electronics continue to evolve with new technology and mounting locations, suppliers and automakers must take care not to create interference conditions between these sensitive on-board receivers and potential sources of noise. Therefore a significant amount of resources are applied in electrical component, systems, and vehicle development to ensure good radio performance. The authors propose a pre-compliance test method that can be used during electronic component and electronic system development to detect and quantify such cases of interference. The test method can be performed prior to vehicle integration to allow for efficient and low cost solutions to potential issues.
