Signal sampling and processing in magnetic resonance applications
In this thesis, signal sampling and processing techniques are developed for magnetic resonance applications, to improve the estimation of magnetic resonance parameters and to reduce experimental acquisition times. Two processing techniques are developed for Nuclear Magnetic Resonance (NMR) …

A predictive adaptive delta modulator
… of the input waveform and an encoding of the signal into a digital sequence. The Kalman Filter does this estimation to filter out some of the noise, thus increasing the fidelity of the output to the original signal. The adaptive delta modulator does the encoding and allows the digital output …

Sampling and quantization for optimal reconstruction
This thesis develops several approaches for signal sampling and reconstruction given different assumptions about the signal, the type of errors that occur, and the information available about the signal. The thesis first considers the effects of quantization in the environment of interleaved, …

Control and simulation of an active suspension system
… to the PC computer, writing software for signal sampling and processing, and developing the test method and algorithm. Results from this system have been validated against two standard methods, a conventional hydraulic shaker and a quarter car test rig with swept sine wave excitation. The …

System Design, Noise Reduction, and Improved Dimension Reconstruction for High Performance Ellipsometry
… noise induced errors are studied, including signal strength, the signal sampling frequency, and the first-order coefficient between the signal variance and mean. This thesis then proposes a signal demodulation method in spectroscopic ellipsometry based on maximum likelihood, in order to …
