DISCRETE DIFFERENTIATION ALGORITHMS WITH INTERMEDIATE SMOOTHING OF INPUT SIGNAL COUNTS
Annotation
Variance of quantization noise at the output of digital differentiating filter is shown to increase drastically with the filter order. Intermediate summation of input signal counts is proposed to reduce the quantization noise effect on derivative calculation errors.
