The properties of the parallel RLC circuit can be obtainedUC3633N
from the duality relationship of electrical circuits and considering that the parallel RLC is the dual impedanceDG201ABK
of a series RLC. From this consideration is immediately obtained the result that the differential equations describing this circuit2MBI300P-140
will be identical to the general form of those describing a series RLC.This is the inverse of the expression for in the series circuit. Likewise,1DI30A-060
the other scaled parameters, fractional bandwidth and are also the inverse of each other. This means that a wide band, low circuit in one topology will become a narrow band,6DI120D-060
high circuit in the other topology when constructed from components with identical values. The and fractional bandwidth of the parallel circuit are given by.
