This paper is devoted to the fault diagnosis of electronic systems by combining logical signals, such as built-in test output, and analog signals, such as voltage, current and temperature. First, the basic inference principles of dependency matrix (D matrix) diagnosis and fuzzy diagnosis are introduced, and the characteristics of their inference op...

An emotion is made of several components such as physiological changes in the body, subjective feelings and expressive behaviors. These changes in speech signal are mainly observed in prosody parameters such as pitch, duration and energy. Hindi language is mostly syllabic in nature. Syllables are the most suitable basic units for the analysis and s...

The spectral analysis of sampled signals is one of the fundamental topics in the signal processing community. The properties and applications of uniformly and periodic nonuniformly sampled one- or two-dimensional signals in the traditional Fourier domain have been extensively studied. As the offset linear canonical transform (OLCT) has been shown t...

Passive time delay estimation in multipath environments is studied in this paper. A novel restrained maximum likelihood (ML) estimator is proposed to estimate the multiple time delays. Unlike traditional ML function which has P global maximum values, restraint conditions limit the ML function of P paths time delays signal with only one global maxim...

A criterion for the input/output-to-state stability of interfered state-space digital filters with saturation arithmetic and external interference is presented. The proposed linear matrix inequality-based criterion ensures the reduction in the effect of external interference as well as confirms the asymptotic stability in the absence of external in...

A modified architecture for minimized power dissipation in the maximum a posteriori (MAP) decoder based on clock gating and toggle filtering is proposed in this paper. Log likelihood ratio (LLR) in the trellis structure of the MAP decoder consumes large power. To minimize the power dissipation, toggle-filtering technique is introduced in the LLR un...

This paper studies the simultaneous fault detection and robust control problem for discrete-time switched systems. A switching law and output feedback-based controller/detectors are designed to meet control and detection objectives. In state-dependent switching framework, the proposed switching law uses only the partial measurable states of the clo...

In this paper, we present a carry-save arithmetic- based coordinate rotation digital computer (CORDIC) engine for computing eight fundamental time-domain statistical features. These features are used commonly in association with major classifiers in remote health monitoring systems with an aim of executing them on a node of wireless sensor network ...

In order to reduce the steady-state misalignment of real-coefficient proportionate affine projection sign algorithm (RP-APSA) for sparse impulse responses, a memory RP-APSA is proposed in this paper by exploiting the historical values of proportionate factors, called MP-APSA. Further, to improve the robustness of MP-APSA and the recently proposed m...

In this paper, the fractional closed-loop system identification problem is addressed. Using the indirect approach, which supposes the knowledge of the controller, both coefficients and fractional orders of the process are estimated. The optimal instrumental variable method combined with a nonlinear optimization algorithm is handled to identify the ...
