A New Definition of Fractional Derivatives Based on Truncated Left-Handed Grünwald-Letnikov Formula with and Median Correction
Figure 2
The original signal (blocks with 1024 samples, blue lines), its fractional derivatives of truncated G-L with different fractional orders ((a) and (c)), and its fractional derivatives of the new method with different fractional orders ((b) and (d)), where the support length of (a) and (b) is 30 and the support length of (c) and (d) is 500.
