    DETAILS OF FUNCTIONS This chapter shows the details of the data analysis functions. Data Analysis Functions DANL_SetOpCondition This function sets the operating conditions of a data analysis function. ■Format short DANL_SetOpCondition (long* plSet, long lSetNum) ■Argument Argument Name Description IN/OUT plSet Operating condition Specify operating conditions for data analysis.
  • Page 14 DANL_GetOpCondition This function acquires the operating conditions of a data analysis function. ■Format short DANL_GetOpCondition (long* plGet, long lGetNum) ■Argument Argument Name Description IN/OUT plGet Operating condition The operating conditions of the data analysis function which are set in the module is stored. storage array Prepare the array elements for the number of elements specified to the number of operating condition storage array elements (lGetNum).
  • Page 15 DANL_FFTSpectrum This function performs spectrum calculation using fast Fourier transform (FFT) for the specified wave. ■Format short DANL_FFTSpectrum (float* pfData, long lPoint, long lWindowType, long lSpectrumFormat, float* pfOutput) ■Argument Argument Name Description IN/OUT pfData Input data storage Specify the start address of wave data to be operated. destination lPoint Data size...
  • Page 16 DANL_DigitalFilter This function performs digital filter operation for the specified wave. ■Format short DANL_DigitalFilter (float* pfData, long lPoint, long lSamplingCycle, DIGITAL_FILTER_SETTINGS_STRUCT DigitalFilterSettings, float* pfOutput) ■Argument Argument Name Description IN/OUT pfData Input data storage destination Specify the start address of wave data to be operated. lPoint Data size Specify the number of the array elements of wave data to be operated.
  • Page 17 ■Operation example of the frequency response filter The following is an example when each filter is applied to the synthetic wave (2) which consists of three waves shown in the composed wave (1). In the following figure, the horizontal axis indicates time and the vertical axis indicates amplitude. *1 The following is an example of an operation.
  • Page 18 ●Band-pass filter A band-pass filter passes signals with frequencies higher than the frequency specified to the cutoff frequency 1 (fCutoffFreqHz1) and lower than the frequency specified to the cutoff frequency 2 (fCutoffFreqHz2). ●Band elimination filter A band elimination filter eliminates signals whose frequencies are higher than the frequency specified to the cutoff frequency 1 (fCutoffFreqHz1) and are lower than the frequency specified to the cutoff frequency 2 (fCutoffFreqHz2).
  • Page 19 DANL_FindCrossPoint This function calculates the number of cross points of the specified wave and a reference value for the number of cross points specified to the maximum number of cross points. ■Format short DANL_FindCrossPoint (float* pfData, long lPoint, float fReferenceValue, long lCrossPattern, long lMaxPoint, long* plCrossData,long* plCrossPoint) ■Argument Argument...
  • Page 20 ■Recognition pattern of a cross point The index of the next cross point is stored to the cross point index storage destination (plCrossData). When the specified wave and the reference value cross between pfData[k] and pfData[k+1] (integer within the range of k0), the index of the cross point to be stored to the cross point index storage destination (plCrossData) is (k+1).
  • Page 21 ● Both rise and fall The total of 4 cross points are detected when '2' or less is set to the number of times of reference value determinations with the DANL_SetOpCondition function. Number of cross points: 4 points Crossing positions: Data[3], Data[7], Data[12], Data[18] Indexes of cross points: 3, 7, 12, 18 Data[19] Data[18]...
  • Page 22 DANL_BoundCompareTest This function compares the specified wave and a check value to determine the upper/lower limit. ■Format short DANL_BoundCompareTest (float* pfData, long lPoint, float fLowerLimit, float fUpperLimit, long* plResult) ■Argument Argument Name Description IN/OUT pfData Input data storage Specify the start address of wave data to be determined. destination lPoint Data size...
  • Page 23 ■Effect of rounding error Setting the number of significant digits of a fractional value does not completely prevent the occurrence of rounding errors. For example, '1.1115' is expressed as '1.1114999...' in the module which handles three-digit significant digits. Therefore, if '1.1115' is rounded off to three decimal places, the result will be '1.111', not '1.112'.
  • Page 24 DANL_AryBoundCompareTest This function compares the specified wave and a check value to determine the upper/lower limit wave. ■Format short DANL_AryBoundCompareTest (float* pfData, long lPoint, float* pfLowerLimit, float* pfUpperLimit, long* plResult) ■Argument Argument Name Description IN/OUT pfData Input data storage Specify the start address of wave data to be determined. destination lPoint Data size...
