  • Abstract
    Linear analog computing elements may be employed to realize a voltage transfer function whose poles and zeros are to be independently controlled. The method is based on the dummy variable technique widely used in analog computer simulation. It requires at most (n + 4) operational amplifiers, n of which are connected as integrators, where n is the degree of the denominator polynomial.
