Abstract
This thesis outlines the design and development of filters applies to medical electronic devices, which leads to a better design and rapid development architecture for the inhibition of electromagnetic interference (EMI). The EMI referred included the device induced and those that existed in our environment. The filters have been constructed with the objective of preventing incorrect data acquisitions and measurements due to the EMI and will increase the reliability and precision of such devices.
A comprehensive introduction of the EMI induced noise and their transmission route is revealed along with a thorough analysis and configuration of an existing consumer product. The new method proposed has greatly reduced the time required for research and design resulting from the fact that adjustments to eliminate noise would no longer be necessary after the design is completed. Recurrent corrections avoided would then accelerate the promotion of the newly designed device into the consumer market.
The implemented filter undergoes laboratory tests, simulations and functional corrections in order to meet all EMI regulations. The final product not only meets the anticipated results, but also gives designers in the field of medical electronic devices a better solution for EMI reductions.
