1. 21. Investigating parameter mapping of the digital musical instrument Force Ghost

   University essay from KTH/Medieteknik och interaktionsdesign, MID

   Author : Nicolas Jonason; [2016]
   Keywords : DMI design; parameter mapping; bandpass; ambient;

   Abstract : This paper investigates the viability of two different mappings of two parameters of the digital musical instrument Force Ghost. The instrument produces sound by having an  ambience (a recording of rain or of waves on the beach) filtered by bandpass filters  whose center-frequencies are controlled by a midi-keyboard.

3. 22. Digital Filter Design Using Semidefinite Programming

   University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

   Author : Moa Samuelsson; Jimmy Johansson; Fabian Samuelsson; [2015-02-11]
   Keywords : ;

   Abstract : 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.

4. 23. Finite Precision Error in FPGA Measurement

   University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

   Author : SHOAIB AHMAD; [2015]
   Keywords : Electrical Engineering;

   Abstract : 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. READ MORE

5. 24. A LTE UPCUL architecture design combining Multi-Blackboards and Pipes & Filters architectures

   University essay from Blekinge Tekniska Högskola/Institutionen för programvaruteknik

   Author : Bohui Jiang Axelsson; [2015]
   Keywords : Multi-Blackboards; Pipes Filters; LTE 4G; Ericsson;

   Abstract : Context. The single blackboard architecture is widely used in the LTE application area. Despite its several benefits, this architecture limits synchronization possibilities of the developed systems and increases the signal operational latency. As a result the DSP (Digital Signal Processing) utilization is suboptimal. READ MORE

6. 25. Improved Positioning of City Buses

   University essay from Lunds universitet/Matematisk statistik

   Author : Nils Bengtsson; [2014]
   Keywords : Mathematics and Statistics;

   Abstract : In order to build an efficient transportation system of the future, public transport needs to be an attractive alternative offering a high quality travel experience. Future digital information systems for public buses will enrich the travelers experience by delivering relevant content - accurately on the right time and place. READ MORE
