ABSTRACT:
A fuel burner control system is disclosed which uses a frequency sensitive diode pump circuit fed by a series of input pulses having a repetition rate within a predetermined range. The diode pump circuit produces an output having a direct current component which exceeds a predetermined threshold when the repetition rate of the input pulses is within a predetermined range. A comparator circuit delivers a pulse signal to a fuel control device when the direct current component exceeds a predetermined threshold.
