1. A method of analyzing a data source, comprising the steps of: training a system using a desired data signal, the training including the step of calculating at least two levels of alarm sensitivity and associated pattern recognition parameters using a pattern recognition methodology; activating a first mode of pattern recognition alarm sensitivity to monitor the data source at a first pattern recognition level of sensitivity; upon activating the first mode of pattern recognition alarm sensitivity also activating a second mode of pattern recognition alarm sensitivity to continue to simultaneously monitor the data source at a second level of pattern recognition sensitivity; generating a first alarm signal upon the first mode of pattern recognition sensitivity detecting an alarm condition; and generating a second alarm signal upon the second mode of pattern recognition sensitivity detecting an alarm condition.
