  1. 16. Digital Filter Design Using Semidefinite Programming

    Kandidat-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Moa Samuelsson; Jimmy Johansson; Fabian Samuelsson; [2015-02-11]
    Nyckelord :;

    Sammanfattning : Abstract This thesis explores an optimization based approach to the design problem of digital filters. We show how a digital filter in the form of a discrete linear time-invariant causal system can be characterized by a non-negative trigonometric polynomial, which in turn can be represented by a positive semidefinite matrix known as Gram matrix representation.

  3. 17. Finite Precision Error in FPGA Measurement

    Magister-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :SHOAIB AHMAD; [2015]
    Nyckelord :Electrical Engineering;

    Sammanfattning : Finite precision error in digital signal processing creates a threshold of quality of the processed signal. It is very important to agree on the outcome while paying in terms of power and performance. LÄS MER

  4. 18. Process and Analysis of Voice Signal by MATLAB

    Kandidat-uppsats, Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Nan Wu; Bofei Wang; [2014]
    Nyckelord :voice signal; MATLAB; filter;

    Sammanfattning : Deliver message by voice is the most important, effective and common method of exchange information for mankind. Language is human specific features and human voice is commonly used tool which is also the important way to pass information to each other. The voice has large information capacity. LÄS MER

  5. 19. Design and implementation of an approximate full adder and its use in FIR filters

    Master-uppsats, Elektroniksystem; Tekniska högskolan

    Författare :Nikhil Satheesh Varma; [2013]
    Nyckelord :FIR filters; bit-level optimization; 4:2 counter; static CMOS; DPL; 65nm process;

    Sammanfattning : Implementation of the polyphase decomposed FIR filter structure involves two steps; the generation of the partial products and the efficient reduction of the generated partial products. The partial products are generated by a constant multiplication of the filter coefficients with the input data and the reduction of the partial products is done by building a pipelined adder tree using FAs and HAs.

  7. 20. Design and analysis of FIR filters based on Matlab

    Kandidat-uppsats, Institutionen för fysik och elektroteknik (IFE)

    Författare :Su Peng; [2013]
    Nyckelord :FIR filter; Matlab; window function; frequency sampling; optimization; amplitude-frequency characterization.;

    Sammanfattning : In digital control system, interference, which is mixed in the input signal, has a great influence on the performance of the system. Therefore, processing of input signal has to be done to get useful signal. Finite impulse response (FIR) filter plays an important role in the processing of digital signal. LÄS MER
