What is Sampling theorem?
The theorem stating that a signal can be reconstructed if it is sampled at a frequency higher than twice its highest frequency component. Also called the Nyquist-Shannon theorem.
Field: AD/DA conversion
Sampling theorem in the explanations
The sampling theorem says a signal can be reconstructed if sampled faster than twice its highest frequency, so 20 kHz content requires more than 40 kHz.
What sampling frequency is needed to sample an analog signa…By the sampling theorem the usable bandwidth is at most half (50 MHz), though about 40% is typical after filter margin.
What does 'MS/s (MSPS)', used to express the conversion spe…The sampling rate must exceed twice the signal's highest frequency (the sampling theorem), or aliasing occurs.
