with respect to

sensitivity
networks have to be constructed and solved. This amounts to excessive
computation.
To avert these difficulties, we notice that these sensitivity networks are
topologically identical. This observation suggests that only one common
adjoint network needs to be constructed for all sensitivity networks.
In the above capacitor case, the magnitude of

to that of the
frequency component of the capacitor voltage
in the adjoint network
provided that the input of

strength. Because the adjoint network of
