[time-nuts] simple explanation of noise spectra with mixing, etc.

2015-02-28 Thread Jim Lux
Is there a handy one pager kind of explanation of noise spectra after some forms of signal processing.. For instance, if you have a oscillator which has a 1/f characteristic, and you mix it with itself, what is the spectra of the output of the mixer. Or if you have a 1/f^3 characteristic
