In radio-astronomy, spectra of noisy signals are often computed using digital auto-correlation techniques. To simplify the design of the many high-speed multipliers and averagers, coarse quantization is employed, using only a few digital levels.
This thesis is a theoretical study of the penalty paid for such coarse quantization in the form of increased output noise. A degradation factor is defined and is calculated for a variety of logic schemes which have been used or proposed.
For each scheme, results are given as a function of sampling rate and it is demonstrated that there is often significant improvement in sampling at rates faster than the Nyquist rate.
A computer simulation technique was developed for verifying the computed results, and for extending the results to complicated schemes where analysis is very difficult. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate
