Energy conservation techniques for wireless sensor networks generally assume that data
acquisition and processing have energy consumption that is significantly lower than that of …

An adaptive controller, Adaptive Positive Position Feedback (APPF) is proposed for the multi-
modal vibration control of frequency varying structures. Spillover phenomena and real-time …

A number of measurement algorithms apply orthogonal signal components obtained by two
orthogonal finite-impulse-response (FIR) filters. The most significant error in orthogonal FIR …

This paper presents algorithms for fast measurement and the nonparametric estimation of
the unknown changing frequency, amplitude, and phase difference of the signals from two …

One important problem of signal processing in measurement systems is designing a filter
that possesses a linear-phase response and, at the same time, has a short transient state …

In spectral analysis, achieving coherent sampling, especially when signals have large
distortion, has been a challenge for many years. This paper introduces three algorithms to …

The measurement of a periodic signal with an unknown changing frequency can be well
done with an interpolation of DFT (discrete Fourier transformation). This paper presents first …

A simple algorithm for the harmonic estimation, in a wide range of frequency changes, with
benefits in a reduced complexity and computational efforts is prescribed. This …

One of the important problems of signal processing is to design a continuous-time filter that
provides both a constant delay over the desired frequency band and a selective magnitude …

Spectral testing has been widely used to characterize the dynamic performances of the
electrical signals and devices, such as analog-to-digital converters (ADCs), for many …
