- SERIES_SPEC (time_series)
- A univariate or multivariate series instances.
- FUNC_PARAMS
-
Name Data Type Description 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_PERIODICITY: Periodicity.
- K_HERTZ: Used with the parameter HERTZ_SAMPLE_RATE to compute the frequency scale in terms of hertz.
The default is K_INTEGRAL.
INCLUDE_COEFF INTEGER [Optional] Indicator to include the calculated αk and βk value columns in the primary result set. A value of 1 includes the columns and a value of 0 does not include the columns. The default value is 0, do not include. The formula for the magnitude at time k in the line spectrum is:
(n/2) * (( αk)2 + (βk)2)
ZERO_PADDING_OK INTEGER [Optional] Indicator to add zeros to the end of the series instances to make computation more efficient. The value of 0 does not add zeroes. A value of 1 does add zeroes. The default is 1. For best performance, let this parameter default to 1. HERTZ_SAMPLE_RATE FLOAT [Dependencies: Only used and required with K_HERTZ.] 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. - INPUT_FMT
