D. K. Upadhyay, R. K. Singh . A Simple Approach to Design Recursive Digital Differentiators and Integrators. International Journal of Computer Applications. 29, 9 ( September 2011), 23-27. DOI=10.5120/3591-4979
In this paper, a simple approach is proposed to design recursive digital differentiators and integrators by applying the concept of time-constant analysis. The time-constant combined with the magnitude response describes the system behavior of a digital differentiator and an integrator. Further, new recursive digital differentiator and integrator designs of first-order systems are also obtained for more accurate or comparable magnitude responses as compared to the existing designs of higher-order systems over wideband. These designs are more suitable for control systems and signal processing applications.
