Abstract
A signal processing technique that allows the flame signal from a first source of flame and the flame signal from a second source of flame to be discriminated from each other when only both the first and second flame signals are viewed by the same flame scanner. The signal from the flame scanner is processed to enhance one or more of the attributes associated with the first flame and is simultaneously processed to enhance one or more attributes associated with the second flame.
