DAPL Data Transformation Commands

DAPL processing commands can perform intensive pre-processing, sending your applications clean data, ready to use.

ABS
Compute the absolute values of a data stream.
BOUND
Restrict outlier values to a range.
RSUM
Compute running sums, continuously or over a window interval.
DELTA
Compute differences of successive values in a data stream.
INTEGRATE
Sum the values in a data stream.
SQRT
Take the square root of values from a data stream.
POLAR
Convert complex number-pairs from rectangular to polar form.
CMAG
Compute the magnitude of a complex number-pair.
CANGLE
Compute the phase angle of a complex number-pair or x-y coordinates.
DECIBEL
Rescale gain data to logarithmic units.

DSP transform and filtering commands also provide useful data transformations.

DAPL expression tasks can perform many useful data transformations defined in terms of ordinary logic and arithmetic.
