WebHow to Analyze the Frequency Content, Page 3 The peak at 10 Hz is still present, but the one at 5.7 Hz is gone; in its place is a peak at 30.3 Hz! Clearly, aliasing errors occurred in the first case, and the sampling rate may still not be high enough. We examine the first two cases to see if they are consistent: o Sampling at 66 Hz yields a frequency component at 30.3 Hz. WebOct 20, 2024 · For example you can easily verify that for the frequency f s = 2 f L + B / 2 which is can be larger than the minimum we computed above, the resulting spectrum shifts will overlapp; there will be aliasing. So bandpass sampling frequencies are selected with care on the resulting spectral shifts. Share Improve this answer Follow braga vs benfica u23
