I am posting this for a friend who does not have net access, so please reply to me via e-mail. The following is a fast fourier transform question. DSPAPfftr2a(n, data, coef) data is defined as a base address for complex data, ad coef is defined as a base addr for sine/cosine lookup table What kind of an array is expected for data ie. is it an array of a pair of numbers, or is it an array with pointers to two other arrays, ...? What is the sine/cosine lookup table? Thanks for any information that you can send. leigh willard leigh@cs.ualberta.ca
