Package Filters.interpolate

Interface Interpolator

All Known Implementing Classes:
PolyInterpolator, PolyInterpolator0, PolyInterpolator1, PolyInterpolator2, SplineInterpolator
public interface Interpolator
Interface for an interpolator. These are a bit like filters in that they have some history and therefore some delay. Designed for use with the decimator, when the decimation factor is non integer.

    Modifier and Type
    Method
    Description
    double
    getOutputValue(double arrayPosition)
    Get an output value for a specific point.

    Set a new array of input data.

  • Method Details

    • getSampleDelay

      double getSampleDelay()
      Get the memory or delay in samples.
      Returns:
      average delay in samples.

    • setInputData

      void setInputData(double[] inputArray)
      Set a new array of input data. The interpolator will probably hold some history from previous data in a buffer.
      Parameters:
      inputArray - array of input data.

    • getOutputValue

      double getOutputValue(double arrayPosition)
      Get an output value for a specific point. 0 refers to the exact position of the first input sample, though there may be buffered data allowing the extraction of data from slightly earlier than that.
      Parameters:
      arrayPosition - picking position. Must be >= 0 and invalid input: '<'= length of input data-1
      Returns:
      value picked from the input array and any history buffer
