Title: Adaptively peaked super-regenerative filter
Inventor: FLANAGAN ROBERT C
IPC: H03H21/00
Filed: 2000-09-13
Abstract: In accordance with one form of the present invention, an Adaptively Peaked Super-Regenerative Filter (APSRF) is provided, which preferably includes an interference suppression system (ISS), a summing block, a phase splitter, one or more variable attenuators, three couplers, an amplifier and a filter. The APSRF  provides for significant narrowing of the bandwidth and a significant increase in the SNR  and Q transfer function of the filter. The output of the amplifier or filter is sampled by one of the couplers and used as a reference sample signal to the ISS. The ISS  includes an adaptive loop, which adjusts the reference sample signal in phase and amplitude to form a replica signal. The replica signal is designed to cancel an input sample signal taken from another coupler and applied to the summing block. An output of the summing block provides an error sample signal to the ISS, which enables the ISS to adaptively optimize the nulling function by adjusting the amplitude and phase of the replica signal. The phase splitter provides a copy of the replica signal having a 180-degree phase shift. This copy is in phase with the input signal, and provides a positive or regenerative feedback signal, which is coupled to the input signal. The copy of the replica signal is passed through a variable attenuator, and by varying the magnitude of the regenerative feedback, the degree of bandwidth reduction can be adjusted over a broad range.

According to a preferred embodiment of the invention (described for illustrative purposes in the context of providing a power supply back up for a cockpit voice recorder (CVR)), the power supply/CVR combination is retrofit in an existing CVR rack. The power supply is, according to the aforementioned preferred embodiment, modular; removable/replaceable; and is "independent" relative to the main aircraft power source and wiring. The power supply/CVR combination is designed to fit into a conventional CVR tray; and the CVR is designed to fit into the modular power supply. Furthermore, according to a preferred embodiment, the power supply is "plug compatible" with the existing electrical connector in the CVR tray and includes circuitry which allows both the power supply and CVR to be tested using the existing CVR test button in the cockpit; and to report faults from either unit using existing aircraft wiring. Moreover, the power supply includes circuitry which automatically electrically disconnects it from the CVR and exposed pins when the power supply is removed from the CVR tray. The CVR and power supply of the preferred embodiment of the invention being modular are easy to install, require no cables, occupy approximately the same space previously occupied by the existing CVR, and have substantially the same center of gravity as the existing CVR. Integrated avionics/back up power supply units are also contemplated by the invention where the units are designed to fit into existing equipment trays to eliminate and/or minimize the need for re-wiring the aircraft.
