    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

  3. 7. Custom Designed Digital Signal Processors Using Bit-Serial Arithmetic

    Författare :Peter Nilsson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; On-Chip Clocking; Digital IF-Filtering; Digital Wideband Filtering; Elektronik; Electronics; Bit-Serial Arithmetic; CMOS; Custom DSP; VLSI;

    Sammanfattning : This thesis presents two prime contributions. First, digital filters for both intermediate and base band filtering for mobile communication are presented. Second, a local clock for on-chip clock generation is introduced. The intermediate frequency filter is a digital alternative to today's analog filters. LÄS MER

  4. 8. 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. 9. 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. 10. Development and Implementation of Cardiac Event Detectors in Digital CMOS

    Författare :Joachim Rodrigues; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Elektronik och elektroteknik; Electronics and Electrical technology; event detection; cardiac pacemaker; sleep- transistors; low-power; ASIC; Neural Networks; Electrogram; Signalbehandling; Wavelets;

    Sammanfattning : This doctoral dissertation presents the development and digital hardware realization of cardiac event detectors. Implantable medical appliances, as the cardiac pacemaker, have progressed from a life sustaining device to a device that considerably improves life quality for all ages. LÄS MER
