To remove aliasing, you need to use an anti-aliasing filter. Quite often, an anti-aliasing filter takes the form of a low pass filter. The issue here is that when you cut the problematic frequencies, you also cut the desirable frequencies above the cutoff point. The best way to deal with aliasing is by preventing it, but if you can’t, your ...

The anti-aliasing would have a cut-off frequency of 20 KHz, but since this is not an ideal filter usually the sampling frequency used goes from 44.1 KHz to 96 KHz, allowing a transition band of at least 2 KHz. An illustration of an anti-aliasing filter being applied to a raw signal is shown below. Say that you want to sample f1 and f2 only.

Using the same audio example, if we want to keep the sampling rate at 44.1 kHz, the anti-aliasing filter will need to have an attenuation of 40 dB at about 22 kHz. With a bandwidth of 20 kHz, the filter will need a transition from 3 dB at down to 40 dB within 2 kHz.
