Post by thread:[PICLIST] Using a PIC for a DSP Low Pass audio fil

I have an application where I wan't to implement a 1 channel low-pass digital audio filter. The freqeuence response of this filter is < 1Khz. Due to the low frequencies and only one channel requirement, I wonder if a processor as simple as a PIC could do the trick. This would save time, since I wouldn't have to deal with a more complicated DSP processor. Has anyone used a PIC for such a function?. What CODEC or A/D, D/A did you use? Any advice, info would be appreciated. -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you. See http://www.piclist.com/#topics

Hi, Microchip has an AN on this topics. Unfortunately, I have only the 17Cxx version at hand (AN540), but it contains the theory and I definitely know there is also a 16Cxx version.
