Investigation of the electromagnetic interference effect on the speed sensor of an aircraft starter generator

An electronic system is compatible with its electromagnetic environment if it satisfies the following two criteria: it does not emit (unintentional) electromagnetic energy above a certain minimum level, and it is not susceptible to malfunction if unintentional electromagnetic energy below a certain level is incident on it. This paper presents a study on the effect that electromagnetic interference has on the speed sensor an aircraft starter generator. An experimental setup was created to generate the radiated emissions, and results were plotted on the oscilloscope. Results obtained by measurement were also compared to the theoretical results.
