In this paper, we present the design of a wide band digital integrator and differentiator. The starting point for this design is the well known backward rectangular numerical integration rule. The rectangular integration formula is modified to get a good low frequency response. The bandwidth of the same is extended to cover a wide range using two clock(More)
In this paper, we consider the design of a digital differentiator and integrator using the natural logarithm series. The proposed class of differentiators and integrators matches the ideal phase response and the magnitude response as closely as possible at low frequencies for orders lower than those reported in the literature. Furthermore, the bandwidth of(More)
In this paper, we propose an IIR design of wideband digital integrator and differentiator. We start our design with an IIR backward rectangular integrator. The response of the rectangular integrator is close to the ideal integrator only in the low frequency region. To improve the response, we connect an IIR filter in cascade with the backward integrator.(More)
In this research work, we propose finite impulse response (FIR) approximation of a digital inte-grator using a non-recursive technique. Since, the magnitude response of integrator at ω = 0, is infinite, it is impossible to have an approximation which includes origin. Anti-symmetric with even tap lengths may be used to approximate the magnitude response over(More)
