ABSTRACT:
An electrical signal processing network includes a high order, two port, three terminal filter, and means coupled to the filter for synthesizing, at a single terminal, an impedance exhibiting the transfer function of the filter. The synthesized impedance can be coupled to a single point in a signal path for filtering signals in accordance with the transfer function of the filter.
