highPass method

void highPass(
  1. int order,
  2. double sampleRate,
  3. double cutoffFrequency, [
  4. int directFormType = DirectFormAbstract.direct_form_II,
])

Butterworth High-pass filter.

Params:

  • order - Filter order (ideally only even orders)
  • sampleRate - Sampling rate of the system
  • cutoffFrequency - Cutoff of the system
  • directFormType - The filter topology. Default direct_form_II

Implementation

void highPass(int order, double sampleRate, double cutoffFrequency,
    [int directFormType = DirectFormAbstract.direct_form_II]) {
  _AnalogLowPass analogProto = _AnalogLowPass(order);
  analogProto.design();
  LayoutBase digitalProto = LayoutBase(order);
  HighPassTransform(cutoffFrequency / sampleRate, digitalProto, analogProto);
  setLayout(digitalProto, directFormType);
}
