SUMMARY
Upsampling and downsampling do not affect the amplitude of the sampled signals. The amplitude remains constant at 1, regardless of the upsampling factor (L) or downsampling factor (M). The discussion clarifies that increasing or decreasing the sampling frequency does not alter the amplitude of the samples, as the amplitude is determined solely by the sampled values x(nT). This is a crucial aspect of signal processing related to the Nyquist rate.
