Apparatus and method for measuring the resonance frequency of a resonant circuit |
摘要 |
A discharge lamp heating circuit resonant frequency measurement procedure measures the voltage or current as the supply voltage is varied stepwise linearly or cyclically within a preset range to find the maximum by averaging measured maxima. Includes INDEPENDENT CLAIMs for equipment using the procedure. |
