Abstract

The thesis is divided into two sections. The first section discusses nuclear quadrupole resonance, relaxation times, experimental procedure, and apparatus, and some data is given. The second section describes the gated digital integrator in detail. The system uses the boxcar integrator technique for analyzing periodic waveforms obscured by noise. The average voltage of a small segment of the waveform is obtained by repeated sampling and is stored in a digital up-down counter. A digital-to-analog converter converts the stored digital number into a voltage to run a recording meter and to provide a feedback signal to compare with the input signal. The sampling point on the input signal is moved across the waveform, and the recording meter plots out the waveform with a greatly increased signal-to-noise ratio.
