Precise tracking of frequency is essential for accurate phasor estimation at off nominal frequencies. In this paper, a simple approach for real time frequency estimation involving interpolation of DFT coefficients corresponding to fundamental and two adjacent bins is presented. In particular, quadratic interpolation method is adopted to estimate the frequency. The quadratic interpolation formulation...
The term “Quality of Speech” in Speech Enhancement techniques is associated with Clarity and Intelligibility. Till now due to the variable nature and characteristics of noise with time and process to process, Speech Enhancement is a difficult problem in Noisy environment. In this paper, we proposed a method to improve the quality of speech based on combination of Digital Audio Effects with Improved...
Dynamic Energy investment funds streamlining gets to be one of the significant worries in the remote sensor system (WSN) directing convention outline, because of the way that most sensor hubs are furnished with the constrained non rechargeable battery power. In this paper, we concentrate on minimizing vitality utilization and amplifying system lifetime for information transfer in one-dimensional (1-D)...
Human pulse rate (PR) can be estimated in several ways, including measurement instruments that directly count the PR through contact- and noncontact-based approaches. Over the last decade, computer-vision-assisted noncontact-based PR estimation has evolved significantly. Such techniques can be adopted for clinical purposes to mitigate some of the limitations of contact-based techniques. However, existing...
Many algorithms have been proposed for harmonic estimation to improve the power quality performance, but till today it is still a challenge for accurate estimation. In this paper an adaptive filtering algorithm called Fast Transverse Recursive Least Square (FT-RLS) is applied for the first time for estimating harmonic parameters. The algorithm has been considered to estimate the amplitudes, phases...
The increasing trend for use of nonlinear loads in power system results in generation of more harmonics and hence deterioration of power quality. This calls for accurate estimation of harmonics in power system so that more effective compensation measures are designed. However, accurate computation of all the harmonics is a challenging problem in power system. Even though many algorithms have been...
