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

    Author : Syed Asad Alam; Oscar Gustafsson; Kent Palmkvist; Yajun Yu; Linköpings universitet; []
    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.

  4. 2. 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

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

    Author : Mohammad Reza Sadeghifar; J Jacob Wikner; Robert Hägglund; Linköpings universitet; []
    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

  6. 4. Charge Sampling Circuits and A/D Converters - Theory and Experiments

    Author : Gang Xu; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pipelined A D converter; sigma-delta modulator; differential difference comparator; 2-step A D converter; FIR filter; analog filter; thermal noise; clock jitter; sub-sampling; RF sampling; current-mode sampling; Charge samling; A D converter; flexible A D converter; Electronics and Electrical technology; Elektronik och elektroteknik;

    Abstract : The analysis of general charge sampling technique is presented in this thesis. Charge sampling integrates input current instead of tracking input voltage to realize high speed and low voltage sampling. The analysis focuses on the performance of general charge sampling circuits for signal capture. READ MORE
