Coefficients of LC passive insertion filters for a voltage response analysis

摘要

In this study we propose a new approach for filter elements calculation when the voltage response is the key parameter. In this case, the source and load resistances must not be part of the filter elements. We propose a methodology to determine the filter elements value far a given filter order and response type. Some simulations are run to sfiow that the results obtained using the standard widely used elements values do not correspond to the expected behaviour. Using the elements values calculated by our methodology, this behaviour is respected. This approach may also be applied to high-pass, band-pass or band-rejected filters using the appropriate transformation from low-pass filter analysis.
