Abstract
A system and method for determining the true electrical characteristics of a device. A codec is configured to measure at least one electrical characteristic of a device connected to a jack and to identify the device based on the measured electrical characteristics. An updateable database is populated with application circuit information and a software routine is responsive to the measured electrical characteristic and configured to adjust the electrical characteristics measured by the codec based on the application circuit information in the database.
