A Simple Approach to Design Recursive Digital Differentiators and Integrators
Dharmendra K. Upadhyay, Rakesh Kumar Singh · International Journal of Computer Applications · 2011
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.
