A b ~ t m c i This paper discusses the many and varied design considerations of a 2-D digital subband filter bank implementation for orthogonal sampling structures, which enables the derivation of only two subbands rather than the usual four. In particular, the design trade-off and overall performance of a Quadrature Mirror Filter pair, in combination with a 2-D diagonal prefilter is explored a...

A simple and reliable inverter is a prerequisite for realizing an efficient active power filter. This paper presents a reduced switch count (RSC) based asymmetrical switched dc sources inverterfor a threephase three-wire (3P3W)shunt active power filter (SAPF). The performance of considered RSCtopology is studied on seven-level asymmetrical configuration with simple level-shifted pulsewidth modu...

Interesting target detection and matching algorithm in complex natural backgrounds images is studied in this paper. Firstly, logGabor filter bank is analyzed, which is consistent with human visual system characteristics. Several kinds of local features from the filter bank can form the integrated feature. Integrated feature congruency (IFC) model is established. And upon compensating noise for ...

This paper proposes a photovoltaic (PV) and battery interfaced series hybrid active power filter (SHAPF), which consists of series active power filter and an LC shunt passive filter. The main benefits of the proposed system provide the compensation against the voltage harmonics, current harmonics and voltage interruption for the whole day. A series active power filter (SAPF) demands a source of...

Received Jan 2, 2017 Revised Mar 2, 2017 Accepted Mar 16, 2017 This paper relates the new topology and simulations of a fully differential CMOS active filter for mm wave band applications. The advantages of the differential topology over the single ended one are discussed and the quality factor is tuned to insure application requirements, including narrow bandwidth and high selectivity due to a...

This paper describes development of adaptive filter algorithm for an Underwater Acoustic Telemetry (UWAT) system for communication between the off shore underwater device (UD) and on-shore communication system. In this system, FSK modulation and de-modulation techniques are used with centre frequency of 38 KHz with baud rate of 300Hz. Adaptive filter algorithm has been developed to compensate t...

We argue that compensating losers is more difficult for immigration than for trade and capital movements. While a tax-cum-subsidy mechanism allows the government to turn the gains from trade into a Pareto improvement, the same is not true for the so-called immigration surplus, if the redistributive mechanism is not allowed to discriminate against migrants. We discuss policy conclusions to be dr...
