Impedance
Tuned Circuits & Filters
- Theoretical impedance of a series resonant circuit is zero –
it is an acceptor circuit and will either short out or
pass signals through at resonant frequency depending on how connected
- Theoretical impedance of a parallel resonant circuit is infinity –
it is a rejector circuit and will either block signals at resonant frequency
or short out signals not at resonant frequency depending on how connected
- These acceptor and rejector circuits form the basis of tuned circuits and filters
