oversampling
  • Sampling above the Nyquist rate, or other minimum sampling frequency, for a given signal. The higher the sampling rate, the more accurate the conversion, and some devices feature rates which are hundreds of times the minimum necessary. For example, if the Nyquist rate for a given signal is 44.1 kHz, then 2X oversampling means that the signal is sampled at 88.2 kHz. In this case 8X over-sampling would yield a rate of 352.8 kHz, and so on. Also spelled over-sampling.
