FM demodulation on DSP 56807 - avinmon - Oct 10 13:12:52 2007



Hi,

I am really new to DSP's. What I would like to is how to demodulate an 
FM signal on a DSP56807 EVM. Now I know that there is a couple of ways 
of going about it , one being generating I and Q values with another 
chip and then doing the complex baseband demodulation using phase 
approximation. What I want to know is how I can demodulate a signal 
generated in Matlab[output from my audio port] on my DSP, is there 
another way of doing this without resorting to the complex baseband 
method. The signal can be assumed to be at baseband before it enters 
the Motorola DSP.

Thanks.
