DRM vs DRM+ | Difference between DRM and DRM+
This page compares DRM vs DRM+ and mentions difference between DRM and DRM+ with respect to various parameters.
Introduction: DRM stands for Digital Radio Mondiale. It is one of the digital audio broadcasting technologies. It is better than AM and FM in terms of audio quality and allows more number of stations. It uses frequencies below 30 MHz for broadcasting and hence DRM transmitters cover longer distances. Hence it is also known by DRM30. DRM transmits data (e.g. RDS type metadata, program associated data) in addition to audio signal data. DRM technical specifications can be downloaded from ETSI website.
DRM+ uses VHF band frequencies from 30 to 300 MHz. DRM+ is upgraded version of DRM.
| Parameters | DRM | DRM+ |
|---|---|---|
| Frequencies | Below 30 MHz | Above 30 MHz in various bands such as 47-68 MHz, 87.5 - 108 MHz, 174 - 230 MHz |
| Channel Bandwidth | Used different BWs from 6.1 KHz to 34.8 KHz which include 4.5 KHz, 5 KHz, 9 KHz, 10 KHz, 18 KHz and 20 KHz. | 96 KHz |
| Audio quality | Good | Better |
