21. Designing for Automated Digital Preservation : Model, Pre-Ingest, and Error Handling
Sammanfattning : With the rapid increase in the amount and complexity of data that is needed to be preserved, manual preservation activities produce complex, lengthy, and costly processes. Therefore, automation of preservation processes, together with modeling of workflows and streamlining, can help reduce costs and enhance the focus on preservation processes. LÄS MER
22. Modeling Analog to Digital Converters at Radio Frequency
Sammanfattning : Det här arbetet handlar om att ta fram beteendemodeller av analog till digital omvandlare avsedda för tillämpningar i radiofrekvensområdet. Det gäller tillämpningar inom telekommunikation men även in test- och mätinstrument där omvandlingen från analoga till digitala signaler ofta är en prestandamässig flaskhals. LÄS MER
23. Custom Designed Digital Signal Processors Using Bit-Serial Arithmetic
Sammanfattning : This thesis presents two prime contributions. First, digital filters for both intermediate and base band filtering for mobile communication are presented. Second, a local clock for on-chip clock generation is introduced. The intermediate frequency filter is a digital alternative to today's analog filters. LÄS MER
24. Low Noise Oscillator in ADPLL toward Direct-to-RF All-digital Polar Transmitter
Sammanfattning : In recent years all-digital or digitally-intensive RF transmitters (TX) have attracted great attention in both literature and industry. The motivation is to implement RF circuits in a manner suiting advanced nanometer CMOS processes. To achieve that, information is encoded in the time-domain rather than voltage amplitude. LÄS MER
25. Studies on Design and Implementation of Low-Complexity Digital Filters
Sammanfattning : 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. LÄS MER
