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
