ABSTRACT: Cascaded Integrator Comb (CIC) filters can perform filtering without multiplying operations and this quality makes practicing engineersand researchers find it highly useful especially for high sample rate signals. Regrettably, the monotonic passband characteristic of the filter generates an unavoidable high passband droop and low attenuation in the stopband which are not acceptable in many applications.Several works have been proposed to improve the performance of CIC filters either in the pass band or stop bandor both in a manner that will provide either smaller pass band error or greater stop band attenuation. This paper presents a new sharpening technique which........

ABSTRACT: Diabetic retinopathy is a microvascular complication of diabetes mellitus, which has a high social cost and requires the intervention of the Medical Bioengineer. This is the reason why the epistemological analysis of emerging trends in the study of diabetic retinopathy is carried out to characterize problematic fields and epistemic matrices that make it possible to integrate an understanding horizon from the field of Medical Bioengineering. The study included three stages: construction of the thematic field; characterization of the elements of the methodology of scientific research programs (hard core, protective belt and heuristics); and reconstruction of the problematic..............

ABSTRACT: An expressive arts way to deal with vogue low power reconfigurable limited motivation reaction (LPRFIR) channel. The LPRFIR is closely resembling personality once the channel arrange is mounted and not changed for express applications and the prudent exchange off between control reserve funds and channel execution is actualized exploitation the anticipated style. For the most part, FIR channel has enormous sufficiency varieties in information record and coefficients. Thinking about the sufficiency of each the channel coefficients and sources of info, anticipated FIR channel progressively changes the channel arrange. Numerical investigation on control reserve funds and channel execution debasement and its trial comes about demonstrates that the anticipated..........
