Illustration of a noisy signal vs.a smooth signal below:
We have to keep in mind this warning wrt using derivative action in regulation/control in such noisy systems:
The big problem with D control is that if you have noise on your signal (which looks like a bunch of spikes with steep sides) this confuses the hell out of the algorithm.
I would add as our deltaT approaches the period of the noise.

Not noisy if you're using frequency modulation.
