Hi,
I’m trying to learn more about noise computation. Basically I’m using the 1.5 MW WTG from the examples with the Aero and CompNoise flags set and the rest as default, so the timestep is 0.005s
Now my question…" is the 1/3 octave spectrum reliable?"
correct me if I’m wrong… how can I “reproduce” a 22000Hz sine wave if I’m time marching with 1/0.005 = 200Hz frequency … I mean, the 1/3 spectrum is always provided up to 20kHz and more but is that ok also if the step is not as small (so the freq as high) as supposed for the “sampling theorem” ? (audio bandwith is approx 22kHz wide, so 1/(2*22k) = 2.3e-5s )
maybe I’ve missed something in the source code…
thank you in advance for your help
