It is possible that the station's transmitter is faulty and they are oiperating on a temporary, lower-powered transmitter with no RDS. Or that the RDS is...

an active filter of some sort is probaby the best way to go. it will yield lower distortion and possible lower error rates, and with careful design, will be...
Hello, My Name is Nate, And I'm going to go in to Broadcasting school, Shortly, And I wanted to learn a few things. Any help at all would be greatly...
... Thank you Josh You mean that implementing a 2nd order sallen key ( by an opamp and some resistors) dont give a good performance ? if yes there are two ...
I seem to think that a stand-alone filter network like the one you propose may work better than trying to take the back way through a phillips IC, which is...
Hi all Just got a techo with some high tech gear to examine & adjust things to get them running properly. We found the RDS injection level was running too low...

HI RDS fan, I am a designer of radio transmitter. And now I am working on a digital radio transmitter with RDS supported. I have some questions to the RDS...
Hi, I don't understand Q1. Q2: RDS subcarrier tolerance is 57kHz +/- 6Hz, which is based on the 19kHz pilot tone +/-2Hz spec Refer EN50067 section 1.1 You...
Hi Jochen, Thanks for your reply, The first question is about SNR to the RDS signal. Let me explain. Assuming the MPX signals is 80dB in SNR. And pilot tone...
Hmmm... still not sure I understand Do you mean receiver SNR? If so, this depends on the receive RF level and the initial RDS subcarrier injection level Do you...
Hi Jochen, Thanks for your patient. I will explain it clearly again. I have follow the EN50067 standard. I designed the transmitter. The RDS modulated signal...
You probably need to look at transmitter specifications and ITU-R recommendations for transmitter performance I'm not familiar with these specs, they're out...
Your 40dB SNR is relative to the RDS subcarrier. The RDS subcarrier at 2kHz deviation is already 31dB down on peak modulation, so you can add that figure to...

Hello there, Do you mean vehicles with RDS for display of station name etc, or do you mean vehicles with the recently launched RDS-TMC traffic information for...
HI Dave, Sorry for delay the discussion. I am new to the digital signal processing design. I have understand a few common of your direction. But let me explain...
