Graphical EMI Modelling Spreadsheet

Consideration is given to the Graphical EMI Modeling Spreadsheet, a computer software system providing a new capability for description and visualization of an EMI (electromagnetic interference) situation, and allowing simple and effective 'what if' considerations for proposed modifications and fixes. The software provides for a spreadsheet display which gives the user the ability to describe the various sources, victims, and coupling paths which make up the overall EMI situation. The spreadsheet provides a method for visualizing the interconnects and interrelations between the various sources, victims, and coupling paths. A graphics window displays the amplitude versus frequency for the input, model, and output for any cell in the spreadsheet. The model window displays data values for each cell models.<>
