Multiplierless Implementation of Digital Colored Noise Generator
Colored noise can be generated by filtering of the white noise. It is a simple task. However, it becomes challenging if high operating speed of the generator is required. The realization of digital filter generally requires one multiplication per coefficient. Therefore, a high operating speed is achieved only with the cost of several generalpurpose multipliers. In this paper, a multiplierless r...

متن کاملColored Noise Inversion in Digital Half toning
A new digital halftone resolution technique, based on a neural network with connection strengths derived from stochastic power spectra, is proposed. Ulichney's "blue noise" spectrum is used as a basis; alternative spectra are also examined. The new technique is compared with standard resolution techniques, ordered dither, Floyd-Steinberg, and dot diffusion. The new technique appears to offer re...
متن کاملDecrease in Hardware Consumption and Quantization Noise of Digital Delta-Sigma Modulators and Implementation by VHDL
A new structure is presented for digital delta-sigma modulator (DDSM). Novel architecture decreases hardware consumption, output quantization noise and spurs in Comparison to previous architectures. In order to reduce the delay, power consumption and increase maximum working frequency, the pipelining technique and the carry skip adder are used. Simulation proposed architecture shows that the qu...
متن کاملMultiplierless Implementation of Rotators and FFTs
Complex rotators are used in many important signal processing applications, including Cooley-Tukey and split-radix FFT algorithms. This paper presents methods for designing multiplierless implementations of fixed-point rotators and FFTs, in which multiplications are replaced by additions, subtractions, and shifts. These methods minimise the adder-cost (the number of additions and subtractions),...
