Is it possible to remove aliasing on a frequency signal in MATLAB SIMULINK? If there is, can someone provide the module in the library. And related studies can be of help too. Thank you in advance!:grin:
 

I don't know about simulink, but can't you just use an LP filter?
 

Hi,

Use an appropriate anti aliasing filter in front of the ADC...to avoid alias signals.

If there are already alias signals you usually can't remove them. The frequencies now are in the "frequency range of interest" thus if you filter away the alias frequencies you attenuate "the good frequencies", too.
