Minimum sampling frequency to avoid aliasing
WebAlias Frequency If fs < 2fm, the high frequency content will be falsely represented by a low frequency component. False frequency is called alias frequency and results from discrete sampling of a signal at fs < 2fm The alias phenomenon is an inherent consequence of a discrete sampling process. Refer to the discussion of folding frequency for http://mmust.elimu.net/BSC(ELEC_COMM)/Year_4/ECE%20421_Comm_Systems_II/Signal_Digitization/Sampling/Sampling_Theorem(1).htm
