WebAliasing occurs when the sampling rate is below the highest frequency in the input, f h. For the first sine function above this is any frequency below 100 Hz. The aliased signal reconstructed will be the difference between the input frequency and the sampling rate. If f s is 80 Hz for the 100 Hz sine wave the resulting aliased signal will be 20 Hz.
