Frekvenskonvertering ved hjelp av punktprøvingsteknikker: En alternativ metode for å flytte bredbåndede RF-signaler opp og ned i frekvens
(Master thesis, 2011)Mange av dagens trådløse systemer benytter frekvenser opp i titals gigahertz området,ofte kalt RF-bånd, til å sende bredbåndede RF-signaler. Siden den digitale enheten somprosesserer RF-signalene opererer på et lavere ... -
Frequency Dependence of Microwave-assisted Electron-transfer Chemical Reactions
(Journal article; Peer reviewed, 2019)In this paper, the electron transfer reactions in the microwave field are studied. A classical theory is developed for a mix of reagents and polar frequency-dispersive and lossy solvent filling vessels excited by microwaves. ... -
Frequency Response of Reflector Arrays
(Master thesis, 2008)This report will investigate the frequency response of reflector arrays. Reflector arrays have two independent cut-off frequencies. One is caused by diffraction from the whole array, another is caused by diffraction from ... -
Frequency-depth-dependent spherical reflection response from the sea surface - a transmission experiment
(Journal article; Peer reviewed, 2018)In academia and the industry, there is an increasing interest in generating and recording low seismic frequencies, which lead to better data quality, deeper signal penetration and can be important for full-waveform inversion. ... -
Full-Custom Sub-/Near-Threshold Cell Library in 130nm CMOS with Application to an ALU
(Master thesis, 2014)This thesis presents a cell library with limited functionality targeting to operate in sub-threshold (350mV) as well as above-threshold (1.2V) voltages utilizing the dynamic speed requirement of the circuit. The sub-threshold ... -
Full-field implementation of a perfect eavesdropper on a quantum cryptography system
(Journal article; Peer reviewed, 2011)Quantum key distribution (QKD) allows two remote parties to grow a shared secret key. Its security is founded on the principles of quantum mechanics, but in reality it significantly relies on the physical implementation. ... -
Full-waveform inversion studies
(Master thesis, 2008)In this master thesis, full-waveform inversion (FWI) was applied to a synthetic, and very complex, geological structure containing a salt body. The main objective was to evaluate the capabilities of FWI to estimate velocities ... -
Fully integrated voltage-controlled LC-oscillators for direct-conversion radio-on-a-chip applications in CMOS technology
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:10, Doctoral thesis, 2005)The development of a 3G/GSM dual-system Radio-On-a-Chip for mobile handsets in CMOS technology depends on the GSM transmitter’s compliance with the receive-band noise mandated by the standard. An integrated direct conversion ... -
