My boss asked me to spread the spectrum of clock, to get better EMI performance.
But i don't know where to find the basic theory of it.
I've found in papers that there are different ways to do it, for example, random modulation and chaotic modulation. But most of them don't give out the clear defination about what the "random" and "chaotic" mean, and how to analysis the spectrum of the modulated signal by a certain defined modulating signal.
Does anybody have done this before? Any help will be appreciated
