Effects of the windowing process, widely investigated by the scientific literature for narrow–band components embedded in white noise, is not sufficiently detailed when signals are corrupted by colored noise. Such a phenomenon can heavily affect the spectral parameters estimation of the noisy signal. In this paper effects of the windowing on the output of analog–to–digital converters with ∆Σ to...

a complete procedure for the design of w-band low noise amplifier in mmic technology is presented. the design is based on a simultaneously power and noise matched technique. for implementing the method, scalable bilateral transistor model parameters should be first extracted. the model is also used for transmission line utilized in the amplifier circuit. in the presented method, input/output ma...

This paper is based on analysis of a common source - common gate low noise transconductance amplifier (CS-CG LNTA). Conventional noise analyses equations are modified by considering to the low output impedance of the sub-micron transistors and also, parasitic gate-source capacitance. The calculated equations are more accurate than calculated equations in other works. Also, analyses show that th...

This paper analyses the output signal-to-noise ratio for a standard noise reduction scheme based on the multichannel Wiener filter and for an integrated active noise control and noise reduction scheme based on the filteredX multichannel Wiener filter, both applied in a hearing aid framework that includes the effects of signal leakage through an open fitting and secondary path effects. In previo...

A Bayesian system identification methodology is proposed for leakage detection in water pipe networks. The methodology properly handles the unavoidable uncertainties in measurement and modeling errors. Based on information from flow test data, it provides estimates of the most probable leakage events (magnitude and location of leakage) and the uncertainties in such estimates. The effectiveness ...

In this article, a new variable leakage flux reverse salient-pole motor (VLF-RSPM) is raised to widen the speed range. The innovation realize both characteristics and by using method of adding magnetic bridges barriers. Firstly, evolution topological structure working principle are introduced. Secondly, based on 2D Finite Element Analysis (FEA), electromagnetic properties noise analyzed in deta...

| This paper examines the potential uses of interband leakage in image coders based on subband decomposition. The approach taken is to use the lowpass subband to predict the signal behavior in the other bands. This information is then used to both inform the coder/decoder as to likely locations for signi cant energy in the highpass bands, and to form a di erence signal that can be coded at a lo...

It was attempted to assess the reliability of DRAMs at the package level. Since the most critical function of a DRAM storage cell is to retain the charge which represents its state, data retention was measured at nominal conditions as a function of refresh time on several 5-V, 4-Mbit memories and one 3.3-V, 16-Mbit memory. Model distributions were fitted to the failure distributions and extrapo...
