HD Radio-DIGITAL NOISE AND INTERFERENCE


BY POPULAR REQUEST!
The BLUE line is the digital interference created by the HD
Radio broadcasting station interfering with the FM stereo subcarrier and surrounding FM stations.
GREEN is the reduced stereo signal to noise ratio.
RED -the two verticle lines at the top are the FCC 200kHz maximum limit for an FM station. Beyond those two verticle RED lines at the top is all the digital noise and interference created on neighboring channels by the digital signal.




PROPONENTS OF THE HD DIGITAL RADIO SYSTEM (MOSTLY THOSE WHO ARE PROFITING) WILL TELL YOU THIS NOISE AND INTERFERENCE DOSN'T MATTER.
