The direct design of a linear phase R R one allows perfectly linear phase, but at the expense of the high filter order, N, and consecuently high computational burden for the given specification. IIR filters, however, can be designed with much smaller orders than their R R couterparts, but at the expense of the non-linear phase. It is, however, possible to design almost linearphase IIR filters f...

This paper proposes an oversampled filter bank, which gives the resultant near perfect reconstruction of input image. An oversampled filter bank structure that can be implemented using popular and efficient fast filter banks to allow subband processing of an input signal with substantially reduced aliasing between subbands. For filters design direct form-II structure FIR filters are used and tr...

The nutrient formulas used for parenteral nutrition are highly complex admixtures of multiple solutions, infused by the IV route to patients who are unable to receive nutrition by mouth or by the enteral route. The administered products contain macronutrients (amino acids, dextrose, and lipids), electrolytes (sodium, potassium, calcium, phosphate, magnesium, chloride, and acetate), micronutrien...

In conventional memory-based multiplication design, the multiplier is replaced by a read only memory (ROM). Since the memory size increases exponentially with the input length, in this paper, a modified hardwareefficient approach for memoryless-based multiplication is proposed. The very large scale integration (VLSI) measure indicates that the proposed approach involves less hardware complexity...

Many different classes of filters have been proposed for removing noise from images (Astola & Kuosmanen, 1997; Bovik, 2000; Kotropoulos & Pitas, 2001). They are classified into several categories depending on specific applications. Linear filters are efficient for Gaussian noise removal but often distort edges and have poor performance against impulsive noise. Nonlinear filters are designed to ...
