    1. w_s = 2 * pi * f_s

    2. 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 or more the highest desired frequency to get proper reproduction

      You need to sample at 2x the desired bandwidth, just bandpass filter the signal appropriately before sampling and you won’t get aliasing.
