Abstract: The paper deals with the implementation of differential filters in the LabVIEW environment. The filters are able to considerably eliminate measurement and quantization noise. The digital filters were shown to be efficient in obtaining good representations of signal derivatives. The quality of derivatives was assessed using the classical method of finite differences and the differential filters. The paper includes an example of a program for real-time filtration. The major objective of the study was to implement the differential filters in real time identification and control algorithms which require appropriate derivatives.
