- There's no real difference between DRM's version
- (sitting next-to the AM signal) and HD's version
- (also sitting next-to the AM signal).
IBOC AM/MW "HD" Radio - Hybrid Mode
http://www.dallas.net/~jvpoll/rfi/AM...BOC_Mask10.gif
- Lower Digital Sidebands {Co-SideBand}
* Analog Host Signal (Mono) {Nested}
+ Upper Digital Sidebands {Co-SideBand}
- Thanks for proving my point. HD sits *next to* the AM signal (+/-
- 10 kHz). Same as DRM sits *next to* the AM signal (+/- 10 kHz).
DRM = Simulcast without Specification {Sans-Mask}
x x x Does Not Equal x x x
IBOC = Intrinsic {Mask} : Nested Analog + Two Digital Co-Sidebands
I still don't see the difference. Both standards are using sidebands,
adjacent to the analog AM signal.
