Shouldn’t it be w>2πF_s?
w_s = 2 * pi * f_s
since you need to sample at 2x or more the highest desired frequency to get proper reproduction, it should be
w>(1/2)w_s
w > (1/2) w_s w > (1/2) 2 pi f_s w > pi f_s
You need to sample at 2x the desired bandwidth, just bandpass filter the signal appropriately before sampling and you won’t get aliasing.
