Erratum：Low-delay and High-functioning Digital Differentiators in the Big Data Era
Takashi Yoshida, Masayoshi Nakamoto, Naoyuki Aikawa · IEEJ Transactions on Electronics Information and Systems · 2018
Since the big data signal has large amount of data, low-delay signal processing algorithm is required. Digital differentiator is one of the digital signal processing tools, and useful to estimate a velocity from the position or obtain the image outline. In this paper, we introduce finite impulse response (FIR) and infinite impulse response (IIR) digital differentiators. The differentiators can achieve a low-delay and high-functioning processing such as low-pass differentiation.
