What sample rate are you planning to use? If it is a multiple of 38kHz it would be somewhat easier than other frequencies. -- glen

And i plan to create out my FM stereo till the 57kHz signal of my RDS. Any help on that in my Matlab on how to write the code or by apply fdatool? Thankz

Your continued allusion to fdatool leads me to believe you don't have a clue. It's like asking, "How do I apply a 9/16" wrench to rebuild my engine?"! -- Randy Yates % "I met someone who looks alot like you, Digital Signal Labs % she does the things you do, mailto://yates(a)ieee.org % but she is an IBM." http://www.digitalsignallabs.com % 'Yours Truly, 2095', *Time*, ELO

Just like we now > have decoders for digital television, when stereo broadcasting > was new there would have been decoders to connect to mono tuners. I've never seen one either, but at one time my dad had an old FM radio that was mono but had a set of outputs at the back where one could supposedly hook up a stereo decoder. He didn't have the decoder though. The radio was tube-based, and dated from the 1950s, IIRC. |
