Abstract:

According to the definition of all-frequency band, a simple formula for measuring and calculating all-frequency band is derived in this paper, i.e. △f=fo/Q and △f=R/2πL. The former is used for measurement and the latter for calculation. The error obtained is smaller than that by the general method.


Key words: Second Order Series Resonance Circuit, All-frequency band
