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.
