Design Considerations

  1. Input signal bandwidth:
    The bandwidth of the signal that must be resolved determines the ADC sampling frequency and the amount of data the code must process.
  2. ADC reference voltage:
    The ADC reference voltage must be selected such that the signal amplitude can be fully captured with good resolution.
  3. Decay coefficient:
    In a single-pole IIR filter, the decay value is the single coefficient that weights the contribution of new samples to the current result. The magnitude of the decay coefficient is between zero and one. A higher decay value results in an earlier cutoff frequency.
