Hi, Can anybody recommend a practical / applied DSP tutorial? The math is unfortunately beyond my abilities. However I would like to=20 understand the concepts such that I could pick up a microcontroller with=20 DSP support and implement basics like a filter, or browse through=20 example source code and understand what is happening. I've watched a few YouTube video series which dive straight into the=20 maths. I appreciate this would be required if I was trying to implement=20 these algorithms myself, but I'm happy using library functions. I'm sure there must be some application notes or similar..=20 recommendations gratefully received. Thanks, David --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
