1. 1. On low-complexity frequency selective digital filters and filter banks

   Författare :Linnea Rosenbaum; Håkan Johansson; Tapio Saramäki; Linköpings universitet; []

   Sammanfattning : En filterbank består av flera filter som arbetar tillsammans för att dela upp en signal i olika frekvensband. De kan också användas för att slå ihop signaler separerade i frekvensplanet till en enda. Sedan tidigt 70-tal har man lärt sig att designa förlustfria filterbankar som alltså inte introducerar några som helst fel i systemet. LÄS MER

3. 2. Techniques for Efficient Implementation of FIR and Particle Filtering

   Sammanfattning : FIR filters occupy a central place many signal processing applications which either alter the shape, frequency or the sampling frequency of the signal. FIR filters are used because of their stability and possibility to have linear-phase but require a high filter order to achieve the same magnitude specifications as compared to IIR filters. LÄS MER

4. 3. Contributions to low-complexity maximally decimated filter banks

   Författare :Linnea Rosenbaum; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Filter banks are systems of several filters with a common input or a common output. They are used whenever a signal needs to be split up into different frequency bands. The first filter banks were introduced in the seventies, and about ten years later it was shown how to design filter banks which do not introduce any errors to the signal. LÄS MER
