Abstract:
A Phasor Measurement Unit (PMU) is a monitoring device, which serves in checking the power system condition by measuring voltage and current phasors along with frequency at a particular node. The basic structure of PMU consists of Synchronization Unit, Measurement Unit and Data Transmission Unit. The Measurement Unit has three components: Anti-aliasing filters, Analog-to-Digital Converter and Phasor measurement Unit/ Processor. An anti-aliasing filter ensures that all the analog signals have the same phase shift and attenuation thus assuring that the phase angle differences and relative magnit

Abstract:
Anti-aliasing filter is widely used in the field of communication and the information collecting system. Generally, anti-aliasing filter is consisted with a low-pass filter, which possesses rapid roll-off rate. In order to ensure that there will be a very smooth amplitude frequency characteristic, the high order Butterworth low-pass filter is adopted to work as anti-aliasing filter. As we know, to design this kind of high order low-pass filter will involve large amount of manual calculation. In order to reduce the manual calculation job, which is meaningless and reduplicated, in this paper, a

Abstract:
Anti-aliasing plays a decisive role in enhancing immersion experience in games and 3D visualization fields. In general, hardware anti-aliasing is not directly compatible with deferred shading. It is challenging to detect geometry edges accurately from sub-pixel to alleviate artifacts. In this paper, we propose an anti-aliasing algorithm of the #-filter anti-aliasing based on sub-pixel continuous edges. It can solve the geometry edges aliasing and the flicker problem in deferred shading. First, the geometry scene with multi-sampling anti-aliasing (MSAA) is rendered to a G-Buffer designed elabor

Abstract The discrete time signal processing requires an anti-aliasing filter at the input and a reconstruction filter at output. Some filters of biquads structure are characterized by a decreasing of the attenuation at high frequencies, caused by the final value of the output resistance of the operational amplifier. In this paper we discuss a design of combined BP filter without mentioned decrease. The proposed filter structure was verified by SPICE simulation.

A novel octave or fractional octave filter design method is presented here. In this method, a cascaded IIR filter is applied to overcome the Finite Word-Length Effect. Compared with the traditional octave filter bank, this method does not require 1/2 extraction or a corresponding anti-aliasing filter. The filter frequency response is improved. Filter attenuation values conform to the standard IEC1260-1995 defined class 0 filters. Simulation and experimental studies shows that the filter bank obtains a more accurate result than does the traditional method, especially in the low-frequency part.

Abstract:
The shafting torsional vibration mode of generator sets reflects dynamic process of the power grid. This paper proposes a novel real-time algorithm for shafting torsional vibration mode decomposition of generator sets, which has excellent time-frequency resolution. The algorithm realizes the signal frequency resolution filtering based on classic infinite impulse response (IIR) filtering. At the same time, the inertia of the narrow-band filtering algorithm is eliminated through multi-period rotation IIR filtering and the time-frequency dynamic resolution of the modal decomposition is realized.

Abstract:
<p>This paper presents the design and simulation results of a novel mixed baseband stage for a frequency band decomposition (FBD) analog-to-digital converter (ADC) in a multistandard receiver. The proposed FBD-based ADC architecture is flexible with programmable parallel branches composed of discrete time (DT) 4<sup>th</sup> order single-bit Sigma-Delta modulators. The mixed baseband architecture uses a single non-programmable anti-aliasing filter (AAF) avoiding the use of an automatic gain control (AGC) circuit. System level analysis proved that the proposed FBD architecture

Abstract:
This paper describes an analysis of multi-stage and multi-rate IIR switched capacitor (SC) decimators using an interactive switched capacitor multi-rate compiler (ISCMRATE). Motivated by the experimental observations, the purpose of this paper is to explore a portion of characteristics for the multi-stage IIR SC decimators, with their implications in the context of a complete IIR SC filter. To overcome the limitations of conventional multi-stage IIR SC decimators, a novel solution has been introduced for the implementation of a multi-stage IIR SC circuit. Based on the statistical approach of t

Abstract:
A system based on virtual instrument was set up to test and analyze the pressure pulsation in centrifugal pump. It had adjustable sampling time length and frequency which can avoid the disadvantages of data loss and redundancy caused by fixed sampling parameters. A signal preprocessing toolkit compiled by LabVIEW was set up, which can anti the aliasing of the signal by use of the low pass filter, decrease the noise in the concerned frequency by the wavelet de-noising and efficiently reduce the error caused by test system. Meanwhile, the signal’s frequency characteristic could be analyzed in th

Abstract:
Nowadays, digital front-end devices are widely used in large number of fields such as electronic appliances. Signals must be presented in an appropriate format, for example, the original analog signals must be converted into digital formats that can be recognized and used by digital equipment. In this paper, the random sampling technique is implemented by original design of a Pseudorandom Signal Sampler circuit for controlling ADC to relax constraints of receiver circuits supporting multiband signal processing. This new idea of using non-uniform sampling technique for multiband signals samplin
