This paper will investigate the effect of digital filtering on the operating time of a generic digital distance relay. Two popular filtering approaches will be considered: the Cosine Filter and the Fourier Filter. The effects of several variables, such as sampling rate, fault location, fault incidence angle, and non-fundamental frequencies, will be discussed. This paper will attempt to discuss ...

In the digital signal processing, digital filtering occupies an extremely important position. This paper introduces the definition and basic principles of FIR digital filters, and the design methods based on MATLAB. After the description of the process of design and simulation of a FIR band-pass filter by means of window function method, the results prove that various performance of the designe...

Radar Signal Processing has been an interesting area of research for realization of programmable digital signal processor using VLSI design techniques. Digital Signal Processing (DSP) algorithms have been an integral design methodology for implementation of high speed application specific real-time systems especially for high resolution radar. CORDIC algorithm, in recent times, is turned out to...

The digital image processing deals with development of digital system that performs operations on a digital image and there manipulation through a digital computer. It’s a subfield of systems and signals but focusing particularly on images. DIP focuses on development of a computer system which is capable to perform processing on an image. This system involves input of digital image, its process...

Visual information transmitted in the form of digital images is becoming a major method of communication in the modern age, but the image obtained after transmission is often corrupted with noise. The received image needs processing before it can be used in applications. This paper represents a robust statistics based filter to remove salt and pepper noise in digital images. The function of the...

Understanding of the runoff generation processes is important in understanding the magnitude and dynamics ofgroundwater discharge. However, these processes continue to be difficult to quantify and conceptualize. In this study,two digital filter based separation modules, the Recursive filtering method (RDF) and a generalization of therecursive digital filter (GRDF) were1991–2002 in the Hableh Ro...

results there was no significant differences between if and conventional mode regarding visibility of mic (p > 0.05). conclusion although using if caused improved visibility of mic, the difference with conventional mode was not statistically different. patients and methods in this cross-sectional study, 2580 digital panoramic images of 18 to 70-year-old patients were inspected for presence of m...

Settling time is one of the most important parameter in design of DLLs. In this paper we propose a new high speed with low settling time Delay Locked Loop (DLL) in which a digital signal processor (DSP) is used instead of using phase-frequency detector, charge pump and loop filter in conventional DLL. To have better settling time, PRP conjugate gradient algorithm is used to optimize delay of ea...

Digital Filter is an important part of digital signal processing (DSP) system and it usually comes in two categories: finite impulse response (FIR) and infinite impulse response (IIR). FIR filter is an attractive choice because of the ease in design and stability. By designing the filter taps to be symmetrical about the centre tap position, a FIR filter can be guaranteed to have linear phase. L...
