  1. 1. On High-Speed Digital-to-Analog Converters and Semi-Digital FIR Filters

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Mohammad Reza Sadeghifar; Linköpings universitet.; Linköpings universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DAC; RFDAC; SDFIR; FIR; semi-digital FIR filter; digital-to-analog converter; D A converter; data converter; mixed-signal integrated circuits; mixer DAC; IQ modulator; transmitter;

    Abstract : High-speed and high-resolution digital-to-analog converters (DACs) are vital components in all telecommunication systems. Radio-frequency digital-to-analog converter (RFDAC) provides high-speed and high-resolution conversion from digital domain to an analog signal. RFDACs can be employed in direct-conversion radio transmitter architectures. READ MORE

  2. 2. Implementation of digit-serial filters

    University dissertation from Institutionen för konstruktions- och produktionsteknik

    Author : Magnus Karlsson; Linköpings universitet.; Linköpings universitet.; [2005]

    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

  3. 3. Sequential complex FIR-structure optimization

    University dissertation from Karlskrona : Blekinge Institute of Technology

    Author : To Tran; Blekinge Tekniska Högskola.; [2005]
    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

  4. 4. Techniques for Efficient Implementation of FIR and Particle Filtering

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Syed Asad Alam; Linköpings universitet.; Linköpings universitet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FIR filter; Particle filter; architecture; ASIC; FPGA;

    Abstract : 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.

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

    University dissertation from Institutionen för systemteknik

    Author : Linnea Rosenbaum; Linköpings universitet.; Linköpings universitet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital filters; filter banks; modulated; FRM; TECHNOLOGY Electrical engineering; electronics and photonics Electronics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik 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
