Abstract: A modulation process with a fully suppressed carrier and input preprocessor filtering to produce an encoded output; for amplitude modulation (AM) and audio speech preprocessor filtering, intelligible subjective sound is produced when the encoded signal is demodulated using the RF Hearing Effect. Suitable forms of carrier suppressed modulation include single sideband (SSB) and carrier suppressed amplitude modulation (CSAM), with both sidebands present.

Abstract: A slotted coaxial shield for high voltage cylindrical air core transformers is described that controls the electric field stress while permitting the rapid extraction of electric energy stored in the shield to improve the output efficiency.

Abstract: A device for charging PFLs (Pulse Forming Lines) on a time scale of a few nanoseconds. The device includes a source transmission line (STL) connected through a switch to a pulse forming transmission line. The source line is initially charged while the PFL is uncharged, and the switch is open. The impedance of the STL is larger than the impedance of the PFL. The impedance of the STL is also tapered in order to effect an energy transfer efficiency approaching 100% from the STL to the PFL. In operation when the switch is closed, energy flows from the source line to the PFL. As the energy and voltage build on the PFL, an output switch closes and delivers the energy of the PFL to the output transmission line section. The impedance of the output transmission line section is matched to the PFL impedance so that all of the energy in the PFL flows into the output section in the form of a pulse.
