Abstract
A method and apparatus for identifying ambient signal data in a test signal data set. A cumulative amplitude distribution of data elements is identified in the test signal data set in order by amplitude values. The data elements comprise frequency values and corresponding amplitude values. A subset of data elements from the test signal data set is identified. The subset of data elements comprises the data elements with the amplitude values greater than a first threshold value. The data elements in the subset of data elements are identified wherein a difference between the amplitude values of adjacent data elements in the cumulative amplitude distribution of data elements is greater than a second threshold value.
