Abstract :
It is well known that the terminating impedance plays an important rôle in the action of a filter. Using a terminating impedance which approximates the negative of the usual iterative impedance is shown to result in transmission not specified by ordinary filter theory in addition to that in the customary pass bands. The effect is essentially one of resonance which can be produced in a suppression band.
