    • getBinsAvgList

      public List<Float> getBinsAvgList()
      
 Averaged FFT bins [dBm].
 Each bin has bandwidth (sample_rate / fft_size) and is averaged over
  a duration of (aggregation_factor * fft_size / sample_rate).
 The FFT bins are centered around center_frequency, i.e.
  first element corresponds to (center_frequency - 0.5 * sample_rate),
  last element corresponds to
   (center_frequency + (0.5 - 1/fft_size) * sample_rate),
  and the center frequency is found at index (fft_size/2).
 The number of FFT bins is fixed to (fft_size).
      repeated float bins_avg = 1;
      Specified by:
      getBinsAvgList in interface SpectrumDProto.AggregatedFFTBlockOrBuilder
      Returns:
      A list containing the binsAvg.

    • getBinsAvgCount

      public int getBinsAvgCount()
      
 Averaged FFT bins [dBm].
 Each bin has bandwidth (sample_rate / fft_size) and is averaged over
  a duration of (aggregation_factor * fft_size / sample_rate).
 The FFT bins are centered around center_frequency, i.e.
  first element corresponds to (center_frequency - 0.5 * sample_rate),
  last element corresponds to
   (center_frequency + (0.5 - 1/fft_size) * sample_rate),

      repeated float bins_avg = 1;
      Specified by:

      Returns:
      The count of binsAvg.

    • getBinsAvg

      public float getBinsAvg(int index)
      
 Averaged FFT bins [dBm].
 Each bin has bandwidth (sample_rate / fft_size) and is averaged over
  a duration of (aggregation_factor * fft_size / sample_rate).
 The FFT bins are centered around center_frequency, i.e.
  first element corresponds to (center_frequency - 0.5 * sample_rate),
  last element corresponds to
   (center_frequency + (0.5 - 1/fft_size) * sample_rate),

      repeated float bins_avg = 1;
      Specified by:
      getBinsAvg in interface SpectrumDProto.AggregatedFFTBlockOrBuilder
      Parameters:
      index - The index of the element to return.
      Returns:
      The binsAvg at the given index.

    • getBinsPeakList

      public List<Float> getBinsPeakList()
      
 Aggregated (peak=max) FFT bins [dBm].
 Each bin has bandwidth (sample_rate / fft_size) and is the maximum
  observed over a duration of
  (aggregation_factor * fft_size / sample_rate).
 The FFT bins are centered around center_frequency, i.e.
  first element corresponds to center_frequency - 0.5 * sample_rate,
  last element corresponds to
   (center_frequency + (0.5 - 1/fft_size) * sample_rate),
  and the center frequency is found at index (fft_size/2).
 The number of FFT bins is fixed to fft_size.

 Important note: intermediate peak results are highly compressed (using a
  logarithmic representation), thus you will almost certainly note
  "steps" in the data. Small values might be smaller than the average
  values or they might even be -inf, due to a low resolution for low
  values.
  In such cases, the average value represents a "better" peak.
  This should not be an issue for strong signals, though.
      repeated float bins_peak = 2;
      Specified by:
      getBinsPeakList in interface SpectrumDProto.AggregatedFFTBlockOrBuilder
      Returns:
      A list containing the binsPeak.
