Means and method for a synchronous network communications system
TLDR
In this article, a new form of signaling based on precise control of the frequency, amplitude, and phase of the waveform of the signal is proposed, which is a unique signature of the transmitting node preventing security breaches.Abstract:
Nodes on a network are synchronized with each other using a clock transfer system (16). The communications channels between the nodes are then measured (164) and calibrated (163) for optimal bandwidth. The optimized channels and synchronization enable a new form of signaling based on precise control of the frequency, amplitude, and phase of the waveform of the signal. Receiving nodes receive information in order to locate the signal at the frequency, phase and amplitude. Precision control (165, 166) of these parameters also serves as a unique signature of the transmitting node preventing security breaches (162) as the signal's characteristics are unique to the transmitting node. The channel is continuously updated with a precision control system (165, 166) to insure that the nodes are not out of phase.read more

Sampling signal analyzer
Michael S Marzalek,Richard Christian Keiter,John A Wendler,Stephen R Peterson,Ronald J Hogan +4 more
TL;DR: The sampling signal analyzer as discussed by the authors synthesizes a sampler drive signal to enable continuous sampling of the input signal and therefore has the advantage over known data sampling signal measurement instruments that it is not triggered directly in response to the level of input signal to be measured, instead, sample timing is based on numerical analysis of the intermediate frequency (IF) signal produced by the sampler.
