[sc-users] Re: Overmodulation in Amplitude Modulation
There's a "splattering" of mathematical representations on the
following link relating to overmodulation.
http://www.ycars.org/EFRA/Module%20B/AMTX%20Prop.htm
The above has the most math that I know of, though some others
explain the process better in layman's terms. The Curtis Roads "The
Computer Music Tutorial" is a must read, of course. Miller Puckette
also has some related info in his book (still a manuscript at this
point, I think) here http://crca.ucsd.edu/~msp/techniques/latest/book-
html/. He was a mathematician, so lots of it here as well. Let me
know if any of this is what you are looking for, otherwise I can ask
some of my colleagues who may know other sources.
Cheers,
Scott

Greetings Colleagues,
I'm searching for papers/books/articles/information relating to:
Amplitude modulation
Amplitude modulation with a complex modulator
"Overmodulation" in ampltude modulation and related spectrum
If anybody knows of any paper/books or documentation on this
subject I would appreciate any pointers.
One specific problem: what controls the amplitude of the sidebands in
Amplitude modulation?? Is there an equivalent to FM's Bessell
functions?
Are there any mathematical formulas related to this process?
many thanks and happy holidays!
