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.
