Satisfactory Essays

The following are brief definitions of terms that will be utilized as a part of this application note: • Noise Shaping Filter or Integrator: The noise shaping filter or integrator of a sigma delta converter distributes the converter quantization noise such that it is low in the band of interest. • Oversampling: Sampling the input signal at a frequency much greater than the Nyquist frequency. Oversampling decreases the quantization noise in the band of interest. • Digital Filter. An on-chip digital filter is used to minimize the signals and noise that are outside the band of interest. • Decimation: Reducing the data rate down from the oversampling rate without losing any information.
