Aliasing and cubase limiters/compressors/distortion

Hi Folks,

I was wondering if anyone knows if the cubase 7 limiters/compressors have in built upsampling to combat aliasing?

If not, does it have another plugin which does the job?

If not, can anyone recommend a waves audio plugin which does the job?

Cheers guys.

come on people! someone must have an answer!??
