minus-square@[email protected]linkfedilinkEnglish8•edit-22 months ago 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
minus-square@[email protected]linkfedilinkEnglish3•2 months ago 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.
Shouldn’t it be w>2πF_s?
w_s = 2 * pi * f_ssince you need to sample at 2x or more the highest desired frequency to get proper reproduction, it should be
w>(1/2)w_sw > (1/2) w_s w > (1/2) 2 pi f_s w > pi f_sYou need to sample at 2x the desired bandwidth, just bandpass filter the signal appropriately before sampling and you won’t get aliasing.
