Realization of nonminimum phase transfer functions using twin-T RC networks

Realization of a second-order nonminimum phase transfer function using the Fialkow-Gerst two-port

network lead to the same design relations governing the element values. Sensitivity consideration shows the practical limitations on this circuit for a specific
Q
of the zeros and for a bounded spread in element values.
