A lowpass antimetric ladder network is transformed into a single-lattice single-sideband crystal filter using simple network equivalences and an asymmetrical frequency transformation. A methodis then given for altering the phase shift independent of both the attenuation and network configuration, and applied so that a crystal in each lattice arm resonates at the frequency of infinite attenuation. Transferring these crystals to outside the lattice results in single-sideband filters of high stability. A frequency transformation involving two attenuation poles is given in an Appendix.
