Having specific signal processing functions is indeed important. I hust have a question about "phase" vs. "angle" spectrum. From browsing quickly through you doc, it seems that the difference is just about *unwrapping the phase*. If that's indeed the case, I've two questions/remarks: 1) is the terminology "phase" vs. "angle" spectrum standardized ? I must say I've never heard of one meaning "wrapped" and the other "unwrapped". I didn't find similar terms in Matlab docs, but I didn't search that thoroughly. 2) Should there be two separate functions for these two, or just one function, with a switch argument `unwrap` ? (I guess it would be True by default) best, Pierre
