Sources of 1/f noise in electrolytes
Abstract
The goal of the research presented in this thesis was to investigate noise power spectra in simple electrolyte systems, specifically related to 1/f type noise. Previous work has been done in this area with conflicting results. Results have been reported observing 1/ f type noise in these systems, while others reported no such spectra. In the latter, excess noise was observed with Lorentzian spectra. We investigated dissolved gas and impurities in the solution as possible sources of 1/ f type noise in an attempt to understand the conflicting results from previous work. We were able to produce spectra exhibiting 1/f type noise as well as those with a Lorentzian shape. In doing this we identified dissolved gas and impurities as individual sources of 1/f type noise. We also observed a cooperative effect when both were present in the solutions.
