1. Studies on Design and Implementation of Low-Complexity Digital Filters
Abstract : In this thesis we discuss design and implementation of low-complexity digital filters. Digital filters are key components in most digital signal processing (DSP) systems and are, for example, used for interpolation and decimation. READ MORE

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

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

4. Contributions to low-complexity digital filters
Abstract : 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. READ MORE

5. Implementation of digital-serial LDI/LDD allpass filters
Abstract : In this thesis, digit-serial implementation of recursive digital filters is considered. The theories presented can be applied to any recursive digital filter, and in this thesis we study the lossless discrete integrator (LDI) allpass filter. READ MORE
