Equivalent Circuit Analysis of a Noise-Reduction Transformer.

This paper describes the equivalent circuit analysis of a noise-reduction transformer. The optimum design and quantitative analysis of noise-reduction transformers have not yet been clarified. To determine a method for realizing the optimum design of noise-reduction transformers, we discuss the noise attenuation characteristics of the noise-reduction transformer on the basis of both experiments and equivalent circuit analysis, taking account of the frequency characteristics of the circuit parameters. We also discuss the dependence of the noise attenuation on the variety of the load.
