Mean square error analysis for the fast LMS-sine algorithm

International Conference on Acoustics, Speech, and Signal Processing, 2002
An analysis is made of the mean square error for the fast least mean square (LMS)-sine algorithm. It is shown that during the very early stages of adaptation the mean square error increases to accommodate the transients which take place in the weight updates.

Image boundary extension with mean values for cosine-sine modulated filter banks

2015 15th International Symposium on Communications and Information Technologies (ISCIT), 2015
We present a mean value extension for cosine-sine modulated filter banks (CSMFBs), which are a class of dual-tree complex wavelet transforms (DTCWTs) and provide rich directional selectivity in image processing. The conventional signal extensions for CSMFBs yield annoying artifacts at the image boundaries due to the directionality being ignored.

Characterization of ΔΣ Converters by Means of the Sine-fit Algorithm

2006 IEEE Instrumentation and Measurement Technology Conference Proceedings, 2006
Performances of ΔΣ converters are evaluated by using algorithms suggested in the IEEE standard 1241, a document which gives indications on the most appropriate procedure to follow for estimating parameters characterizing generic analog?to?digital converters (ADCs).

Accurate ADC dynamic testing by means of the three-parameter sine-fit algorithm

2009 IEEE 15th International Mixed-Signals, Sensors, and Systems Test Workshop, 2009
In this paper it is shown that the effective number of bits (ENOB) of an analog-to-digital converter (ADC) can be accurately estimated by means of the three-parameter sine-fit algorithm, when the normalized frequency is a priori estimated by the interpolated discrete Fourier transform (IpDFT) method with maximum sidelobe decay windows.

Solitonlike solutions of the elliptic sine–cosine equation by means of harmonic functions

Journal of Mathematical Physics, 1978
Exact solutions of the elliptic sine–cosine equation ∂2ψ/∂x2+∂2ψ/∂y2=sin(ψ+g) are derived in two space dimensions with the aid of a new Bäcklund transformation and by exploiting the properties of the harmonic function g (x,y). Two generating formulas are developed which allow us to generate without additional quadratures an infinite number of real ...

Accurate dynamic characterization of sine-waves by means of the ADS1258EVM-PDK KIT

2014 6th European Embedded Design in Education and Research Conference (EDERC), 2014
This paper is focused on the estimation of the dynamic parameters of a sine-wave by means of the ADS1258EVMPDK kit. The dynamic parameters are the SIgnal-to-Noise And Distortion (SINAD) ratio, Effective Number Of Bits (ENOB), Total Harmonic Distortion (THD) ratio, and Spurious Free Dynamic Range (SFDR) ratio.

Construction of solutions of the sine-Gordon equation by means of fredholm determinants

Physica D: Nonlinear Phenomena, 1983
The author makes the following introductory statement: ''The famous ''soliton equations'' or ''nonlinear evolution equations solvable by the inverse spectral transform'' are a class of nonlinear differential (or difference) equations which share the following three outstanding properties: There exists a transformation to a form which is essentially ...

Image Boundary Extension With Mean Value for Cosine–Sine Modulated Lapped/Block Transforms

IEEE Transactions on Circuits and Systems for Video Technology, 2019
We present a novel image boundary extension and mean value extension (MVE) for directional lapped transforms, particularly cosine–sine modulated lapped transforms (CSMLTs). Lapped transforms are usually used with an extension technique, such as periodic extension (PE) or symmetric extension (SE), for nonexpansive convolution at signal boundaries.
