Sažetak:
The basic characteristic and benefit of the DRM digital system is adoption of digital technology in revitalization of AM broadcasting bands below 30 MHz. The DRM system is designed as an eventual replacement for current analog AM broadcasting, keeping in mind the coexistence of these new digital transmissions with current AM broadcast, because the changeover from analog to digital broadcasting can be phased in over a period of years. In this paper we discuss the coexistence of analog AM and digital DRM systems. Using the worldwide located trial DRM transmitters as generators of the DRM signal, and laboratory model of DRM receiver we have measured mutual interference of the systems. The paper discusses these measurements and gives some conclusions related to determination of an optimal level of the DRM signal to provide good quality DRM service whilst avoiding a significant impact on the existing analog AM service.
