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

    Författare :Linnea Rosenbaum; Håkan Johansson; Tapio Saramäki; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital filters; filter banks; modulated; FRM; Electronics; Elektronik;

    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. Implementation of digit-serial filters

    Författare :Magnus Karlsson; Mark Vesterbacka; Lars Wanhammar; Wlodek Kulesza; Viktor Öwall; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Implementation; CMOS; Low Power; High Speed; Wave Digital Filter WDF ; FIR filter; Signal processing; Signalbehandling;

    Sammanfattning : In this thesis we discuss the design and implementation of Digital Signal Processing (DSP) applications in a standard digital CMOS technology. The aim is to fulfill a throughput requirement with lowest possible power consumption. LÄS MER

  4. 3. Contributions to low-complexity digital filters

    Författare :Oscar Gustafsson; Keshab K. Parhi; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : In this thesis we discuss design and implementation of low-complexity digital filters. Digital filters are key components in many digital signal processing (DSP) systems. Typical applications include interpolation, decimation, and noise suppression.The work presented in the thesis can be divided into four parts. LÄS MER

  5. 4. Synthesis and Realization of High-Speed Recursive Digital Filters

    Författare :Håkan Johansson; Lars Wanhammar; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Recursive digital filters restrict the sample frequency at which an implementation of the filters can operate. This bound is determined by the ratio between the number of delay elements and the operation latency in the recursive loops of the filters. LÄS MER

  7. 5. Techniques for Efficient Implementation of FIR and Particle Filtering

    Författare :Syed Asad Alam; Oscar Gustafsson; Kent Palmkvist; Yajun Yu; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FIR filter; Particle filter; architecture; ASIC; FPGA;

    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
