Abstract

LC circuit resonance frequency measurement often requires the use of professional analysis instruments such as LCR meters, vector network analyzers, but currently such instruments on the market are expensive, and it is difficult for non-professional institute personnel to access. Here comes unnecessary trouble. In view of this situation, a test method for measuring the resonance frequency using only a digital storage oscilloscope is proposed. Using the impulse signal to obtain the system response, the response waveform period can be observed through the oscilloscope.
