Analog Sample Rate

The Nyquist sampling theorem indicates that a minimum of two samples per cycle of the data bandwidth are required to reproduce the sampled signal with no data loss.  Essentially this eliminates the possibility of introducing an aliasing component into the sampled data but does not guarantee that an accurate signal waveform will be recorded and can be reconstructed post-collection.  Accurate data reconstruction of biomedical signals normally requires at least five data samples per maximum data cycle bandwidth.
