Part Number: TMS320C203
I've been in analog RF design all my life. A modem vendor has told me that the audio filter in a new SSB radio absolutely has to be an FIR filter, probably with about 89 taps. This would be a low pass filter, less than .5 dB ripple, pass band to 2800 Hz. Stop band from 3000 Hz to 5000 Hz. I know very little about DSP and I'm searching for a reference design which would fit the bill or can be modified to fit the bill. Is there such a thing in the vast TI library of information? Or could I get pointed to a suitable processor and take it from there? I'd like to avoid having to contract this out.
thank you.
