A signal processing method and apparatus for analyzing operation of a combustion burner. Responsive to a signal produced by a flame sensor which monitors a burner flame, a fluctuational component of the signal is converted into an extremum function having a floating extremum point with a frequency coordinate which varies in the frequency domain with changes in combustion conditions. A current extremum value of the extremum function is calculated. Then, in relation to the current extremum value, a value of at least one parameter of the extremum function is calculated, such function being related to the combustion characteristic. The apparatus comprises a processor and memory coupled thereto, the memory having stored therein a plurality of instructions which, when executed by the processor, cause the processor to perform the aforementioned operations. |
