Every non-linear mixing of signals gives you sum and difference frequencies. It's less a weird PLL thing and more a weird trig function thing.

- kayson 5mo agoIts not even a non linear thing. Its a sampling thing. Even ideal sampling exhibits aliasing. https://en.wikipedia.org/wiki/Nyquist%E2%80%93Shannon_sampling_theorem https://en.wikipedia.org/wiki/Nyquist%E2%80%93Shannon_sampli...
- regularfry 5mo agoYes, and. You can look at aliasing as a special case of heterodyning. Sampling is a nonlinear mixing.
