  • Ideally the BW is defined as the -3dB point of the frequency response of the system. Sampling Theorem states that you need at least two samples per cycle in order to minimally figure out the frequency. This does not mean you can measure the amplitude! That is why when your working with digital signals you have to take into account all the harmonics that build up a waveform. In that case its common practice to need 5-10x the fundamental frequency in terms of the amount of samples.

No public wish lists :(
