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

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

    Abstract : 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. READ MORE

  4. 2. Contributions to low-complexity digital filters

    Author : Oscar Gustafsson; Keshab K. Parhi; Linköpings universitet; []
    Keywords : ;

    Abstract : 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. READ MORE

  5. 3. Implementation of digit-serial filters

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 5. Sequential complex FIR-structure optimization

    Author : To Tran; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite Impulse Response FIR ; Digital filter design;

    Abstract : Over the past 40 years, the area of digital signal processing and filtering has undergone a rapid development. Today, most of the filtering tasks, that before were performed by using analog technology, have been substituted with inexpensive and, often, more reliable and flexible digital solutions. READ MORE
