Normally the operational amplifier is used as a component in active filter design. The goal for future components in filter design is large bandwith and the use of low supply voltages. The use of current-mode instead of voltage-mode circuits gets a step closer to the required …
… of most fresh waters and the Baltic Sea. The waste water can be cleaned by filter materials, which have a high P-retention ability and which after saturation may be used as fertilizers. Four potentially suitable filter materials were tested in batch- and column experiments in …
… method that does not require much maintenance, could be the use of reactive filters with filter materials consisting of industrial residues or other cheap mineral based materials. Dissolved metal ions are removed by reactive filters through the processes of ions binding to …
… methods for identifying states in robot models. Both linear and non-linear filters exist among these methods and are compared to each other. Advantages, disadvantages and problems that can occur during tuning and running are presented. Additional measurements from accelerometers …

… of Kramfors has since 2003 had problems of fast clogging of the slow sand filters. As the clogging appears more often, they must be cleaned more frequently which has made the drinking water preparation difficult. Wintertime it has sometimes been impossible to clean the filters …
… skäl ofta inte användas. I denna uppsats har något som kallas inversa filter undersökts som möjligt alternativ. Dessa skapas från ett uppmätt rumsimpulssvar och appliceras på signalen till högtalaren genom faltning. Det filter som har använts baseras på teori av Kirkeby, och för …
… how different strategies in choosing attribute values affects junk mail filtering. We used two different variants of a naïve Bayesian junk mail filter. The first variant classified an e-mail by comparing it to a feature vector containing all attribute values that were found in …
… signaler på ett någorlunda kontrollerat sätt i ett labbnät krävs ett filter. Filtret är nödvändigt för att inte förstöra signalgeneratorn som skickar ut dessa frekvenser mot elnätet. Arbetet som ligger till grund för rapporten går ut på att konstruera ett effektivt filter och ta …
… och i den finns enbart 3 stycken multiplikatorer lediga. Utgången från vårt filter ska ha samma frekvens som innan översamplingen, vi kommer därför att bygga ett FIR-filter som decimerar signalen. Vi valde detta filter för att kunna utnyttja symmetri och minimera antalet …
… detection. The hypothesis was that the signal-noise ratio would decrease if a filter and a proper installation were used for the detector. Some experiments were executed to determine what kind of filter were the most suitable for each application and how these could be …
