라디오방송 주파수 관련 자동차 전자파방사 규격에 대한 연구

Notwithstanding the measured values concerning narrowband electromagnetic radiation from vehicles excess the limits over all frequencies, the signal strength measured at the vehicle broadcast radio antenna is less than 20 dB㎶, then the vehicle shall be deemed to comply with the limits for narrowband emissions and no further testing will be required in Europe regulations ECE R 10. But narrowband disturbance sources are vehicle electronic components which include clocks, oscillators, disgitals as well as broadcast radio. And this study indicate that narrowband electromagnetic specifications needed to be revised.
