| ZERO_PADDING_OK |
Integer |
[Optional] The number of zeros to add to the end of a given series to achieve a more efficient computation of the Fast Fourier Transform coefficients. A value of 1 means true, and a value of 0 means false. The default is 1. For best results, use 1. |
| FREQ_STYLE |
String |
[Optional] The format or values associated with the x-axis of the output. Choices are:- K_INTEGRAL: Integer representation.
- K_SAMPLE_RATE: Integer normalized to number entries, with ranges from -0.5 to +0.5.
- K_RADIANS: Radian ranges from -π to +π.
- K_HERTZ: Frequency in hertz. Must be used in conjunction with HERTZ_SAMPLE_RATE.
The default is K_INTEGRAL.
|
| HERTZ_SAMPLE_RATE |
FLOAT |
[Dependencies: Only used and required with the FREQ_STYLE(K_HERTZ) parameter.] The sample rate as a floating point constant, in hertz. A value of 10000.0 indicates that the sample points were obtained by sampling at a rate of 10,000 hertz. |
| ALGORITHM |
String |
[Optional] The user-defined algorithm that bypasses the internal DFFT planner, and influences the core DFFT algorithm associated with the primary DFFT calculation. Choices are COOLEY_TUKEY, or SINGLETON. When this parameter is not present, then the internal DFFT planner selects the most efficient algorithm for the operation.
For best performance, do not include this parameter. Instead, let the internal DFFT planner to select the best algorithm.
|
| HUMAN_READABLE |
Integer |
[Optional] Indicator to determine whether the produced output rows are in human-readable or plottable form, or the output is in the raw-form. Human-readable output is symmetric around 0, such as -3, -2, -1, 0, 1, 2, 3. Raw output is sequential, starting at zero, such as 0, 1, 2, 3. A value of 1 means true, and the output is in human readable form. A value of 0 means false, and the output is in raw form. The default is 1.
