  1. 21. Development of a Digital Universal Filter Bank

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och System

    Författare :Mats Larsson; [2016]
    Nyckelord :;

    Sammanfattning : This is a master's thesis project, which is a part of the Master Programme in Electrical Engineering at Uppsala university. When developing a product or performing measurements, it is sometimes necessary to remove some content of a signal. LÄS MER

  3. 22. Utveckling av prototyp för uppmätning av blodflöde med Dopplersensorer

    M1-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Tomas Johansson; [2016]
    Nyckelord :Doppler; NFC; FIR-filter; blodflöde; Raspberry Pi; AGC; fönster;

    Sammanfattning : The current most common methods for measuring a blood vessels flow with Doppler technique requires a cable between the patient and measuring instrument. In today’s technology and the progress made in microelectronics have made it possible to manufacture ultrasonic transmitters and receivers, control electronics and antennas small enough for them to be integrated in a probe attached to the blood vessel.

  4. 23. 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.

  5. 24. 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

  7. 25. Low Power Design Using RNS

    Master-uppsats, Linköpings universitet/Elektroniksystem; Linköpings universitet/Tekniska högskolan

    Författare :Viktor Classon; [2014]
    Nyckelord :residue number system; RNS; low power; ASIC;

    Sammanfattning : Power dissipation has become one of the major limiting factors in the design of digital ASICs. Low power dissipation will increase the mobility of the ASIC by reducing the system cost, size and weight. DSP blocks are a major source of power dissipation in modern ASICs. LÄS MER
