[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!
