Many methods exist for cardiac and neural signal feature extraction and identification, but a published method for validation of therapeutic medical devices by computer analysis of their signals can be seldom found. This paper presents a simple, fast algorithm to extract the electrical stimulation including pulse width, exponential decay, and time between pulses from neurostimulators, pacemaker...

Models of integrated circuits (ICs) allow printed circuit board (PCB) developers to predict radiated and conducted emissions early in board development and allow IC manufactures insight into how to build their ICs better for electromagnetic compatibility (EMC). A model of the power delivery network, similar to the ICEM or LECCS model, was developed for a microcontroller running a typical progra...

This article presents the design, modeling, and fabrication of a printed log-periodic biconical dipole array antenna (PLPBDA) for electromagnetic compatibility (EMC) measurements. The proposed structure used bow tie-shaped dipoles instead typical to achieve size reduction 50% bandwidth enhancement 170% with help PCB technology. Furthermore, balanced feeding method modifications in dimensions we...

This paper describes modelling a step-down chopper designed for photovoltaic application to study its performance of electromagnetic compatibility (EMC) in conducted mode. The EMC measurements attended at this stage have shown that the buck converter is harmful device environment. Indeed, fast-switching operation leads higher levels and radiated interference (EMI) subsequently facilitates coupl...

A fiber access communication system is developed to cater for the need of network communications industry. In this paper, the basic framework of the system is described; with regards to the characteristics of the system, firstly the electromagnetic interference approaches of the whole system are discussed. Emphasis is laid on the engineering analysis and discussion of the interference sources o...

Electromagnetic compatibility (EMC) has become much more important especially over the last decade due to incorporating advanced driver assistance and electric propulsion systems into conventional vehicle architecture. shielding is a conductive barrier used for protecting electronic circuits against external electromagnetic interference (EMI). Shielding effectiveness (SE) measure of performance...

Better prediction of electromagnetic compatibility (EMC) for components is becoming a topical demand, due to technology improvements. It is requested by integrated circuit (IC) manufacturers as well as by equipment integrators. The French UTE standardisation group has proposed an EMC modelling methodology for ICs, called ICEM (Integrated Circuit Electromagnetic Model). This proposal improves an...

The rigorous uncertainty estimation in Electromagnetic Compatibility (EMC) testing is a complex task that has been addressed through a simplified approach that typically assumes that all the contributions are uncorrelated and symmetric, and combine them in a linear or linearized model using the error propagation law. These assumptions may affect the reliability of test results, and therefore, i...

Electromagnetic Compatibility (EMC) filters are one of the main solutions for dealing with disturbances generated by power inverters. However, they show series/parallel resonances that introduce variations in impedance seen from grid. Consequently, some cases, these have low impedances at resonance frequencies, which can affect Narrowband Power Line Communications (NB-PLC) due to notching effec...
