Postprocessing Filtered Signals (Digital Filter Design Toolkit)

After you deploy fixed-point filter coefficients to the target hardware, the output data uses a fixed-point representation. To convert the output signal of the fixed-point filter into floating-point representation, you must process the fixed-point signal using the DFD FXP Postprocessing VI.

Refer to the Step 6 - Postprocessing (Lowpass) VI in the labview\examples\Digital Filter Design\Case Studies\Single-Rate Filter directory for an example that demonstrates how to postprocess a filtered signal.
