Electromagnetic interference (EMI) generated by electric vehicles (EVs) can compromise the reception quality of AM signals. This paper explains some effects of EMI on AM reception and audio quality in EVs, and the importance of EMI mitigation, with the help of field test data using EVs. The reception performance of analog AM and all-digital AM In-Band On-Channel (IBOC) digital radio1 signals is then briefly compared based on results from analysis and field measurements. Finally, field test results for internal combustion engine (ICE) vehicles and EVs demonstrate the robustness of all-digital AM signals and the superior AM audio experience provided by AM IBOC digital radio technology.
