pl.polsl.rtsa.api.dto.SignalData
Record Components:
timestamp - When this result was created.
timeDomainData - Array of voltage samples in time domain (V).
freqDomainData - Array of FFT magnitude values.
sampleRate - Sampling rate used to capture this data (Hz).
statistics - Pre-computed signal statistics.
public record SignalData(Instant timestamp, double[] timeDomainData, double[] freqDomainData, double sampleRate, SignalStatistics statistics) extends Record
Data Transfer Object representing a complete signal analysis result. Immutable record for thread-safe access from UI thread.

  • Method Details

    • getDurationSeconds

      public double getDurationSeconds()
      Returns the duration of the time-domain data in seconds.

    • getFrequencyResolution

      public double getFrequencyResolution()
      Returns the frequency resolution of the FFT (Hz per bin).

    • getNyquistFrequency

      public double getNyquistFrequency()
      Returns the maximum representable frequency (Nyquist frequency).

    • getSampleCount

      public int getSampleCount()
      Returns the number of samples in the time domain.

    • getFrequencyBinCount

      public int getFrequencyBinCount()
      Returns the number of frequency bins.

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with '=='.
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.
