A set of enhanced digital integrators (EDI) with improved accuracy via genetic algorithms are proposed in this paper. By specifying a desired power for the integrator to be sought and the interval for comparison, chromosomes consisting of parameters of the enhanced digital integrator are then searched by the genetic algorithm based on root mean squared (RMS) error between the original integrato...

New IIR digital differintegrators (differentiator and integrator) with very minor absolute relative errors are presented in this paper. The digital integrator is designed by interpolating some of the existing integrators. The optimum value of the interpolation ratio is obtained through linear programming optimization. Subsequently, by modifying the transfer function of the proposed integrator a...

Quantum mechanics is an excellent technique to counter and study the effect of noise in any system. A digital integrator can be designed with the help of quantum mechanics by passing a known signal ( ) to a known digital integrator, with impulse response ( ) and then, the output of this integrator ( ) is given to the input of a known quantum system (specified by its Hamiltonian ( ), perturbatio...

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...

In our world, communication systems play an important role in day to day life. In wireless and wired communication systems, signals are to be upsampled at the transmitter. Digital up converter (DUC) is a sample rate conversion technique which is widely used to increase the sampling rate of an input signal. The digital up converter converts low sampled digital baseband signal to a pass band sign...

| Recursive digital integrators (RDI) approximating the analog integrator frequency response are designed. Generic structures are considered and a set of designing rules is proposed. With this approximation it is possible to shape the introduced modulus and phase distortion in a desired way and it is possible to eliminate the trapezoidal integrator modulus distortion [1-3] while maintaining the...
