Find Resonant Circuit Values
BACK

Series Circuit
Allows Only the resonant frequency to pass through.
When placed across a feed-line, acts as a short circuit to the resonant frequency.
Parallel Circuit
Blocks the resonant frequency from passing through.
When placed across a feed-line, permits the resonant frequency to pass through.
