Hey peeps,

I have another question regarding "The Theory and Technique of Electronic Music". It is not directly related to pd, but I guess that many of you will know this stuff and might be able to help me. I hope it is ok.

In the last paragraph of 9.1 (http://msp.ucsd.edu/techniques/latest/book-html/node164.html) the frequency of the modulating signal is defined as having negative frequency (in the book -kω), why is that the case? wouldn't a sinusoid with positive frequency kω also give us two partials at 0 and 2kω?

Cheers,

Maxi
