22. Frequency Analysis of Sampled-Data Systems Applied to a Lime Slaking Process
Sammanfattning : Single-rate and multirate sampled-data (SD) systems as well as linear time periodic (LTP) systems with discrete jumps are analyzed in the frequency domain. The focus of the analysis is both on rejection of disturbances and on robust stability properties. LÄS MER
23. Stability of Low-Frequency AC Railways : Models and Transient Stability
Sammanfattning : Low-frequency AC railway grids are unique in the sense that a only few countries around the world uses them, still however, they are an important parts of their countries infrastructures. Due to the usage of a dierent frequency than the public grid of the country, conversion of frequency is needed for the interconnection. LÄS MER
24. A/D Conversion for Sensor Systems
Sammanfattning : Today, an important field for circuit design research is advanced mixed mode CMOS circuits for the most varying purposes. By designing these for implementation in basic and cheap digital technologies, building blocks for advanced systems are achieved. LÄS MER
25. MMIC-based Low Phase Noise Millimetre-wave Signal Source Design
Sammanfattning : Wireless technology for future communication systems has been continuously evolving to meet society’s increasing demand on network capacity. The millimetre-wave frequency band has a large amount of bandwidth available, which is a key factor in enabling the capability of carrying higher data rates. LÄS MER
