21. Power Efficient Digital Decimation Filters for Sigma-Delta ADCs
University essay from Institutionen för systemteknikAbstract : The development of integrated circuit technology seen in the last decades has enabled a large variety of battery operated equipment to emerge, such as smallsensors and medical implants. These applications often has low requirements on sampling frequency but require a very low power consumption to achieve a longbattery life. READ MORE

22. Real-time rendering of very large 3D scenes using hierarchical mesh simplification
University essay from Institutionen för teknik och naturvetenskapAbstract : Captured and generated 3D data can be so large that it creates a problem for today's computers since they do not fit into the main or graphics card memory. Therefore methods for handling and rendering the data must be developed. This thesis presents a way to pre-process and render out-of-core height map data for real time use. READ MORE

23. Design and implementation of a decimation filter using a multi-precision multiply and accumulate unit for an audio range delta sigma analog to digital converter
University essay from Institutionen för systemteknikAbstract : This work presents the design and implementation of a decimation filter for a three bits sigma delta analog to digital converter. The input is audio with a oversampling ratio of 32. Filter optimization and tradeoffs concerning the design is described. The filter is a multistage filter consisting of two cascaded FIR filters.
