Abstract: This invention pertains to a method by which the frequency and the modulation characteristics of a wire or wirelessly transmitted signal can be identified in a matter of milliseconds with significantly higher speed and accuracy than with existing or prior art receivers and spectrum analyzers, without erroneous image signals. Such signals can be then demodulated and decisions made based upon the demodulated data. The system then can be reconfigured to act as a transmit-receive module, with the transmit frequency enabled to address many different applications. This has applications in, terrestrial and satellite communications, and defense.

Abstract: This invention describes a method by which Broadband Spectrum Analysis can be performed in the RF and Microwave frequency range with significantly higher speed, accuracy, and flexibility than existing RF and Microwave Spectrum Analyzers. This is done by eliminating the need for the filtering of the incoming signal, a process called preselection that needs to track in frequency with the scanning local oscillator in the instrument. By eliminating this requirement, this invention makes possible the identification and analysis of very broadband signals in a single sweep using an Adaptive Sweep Methodology and a Simultaneous Sweep capability that the present invention makes possible.

Abstract: This invention describes a method by which a low cost low phase noise Phase Locked Loop or Phase Locked Loop based Frequency Synthesizer can be realized. The new method, called a Translational Phase Lock Loop or TPLL, allows the conversion of a traditional voltage controlled oscillator or VCO signal so that the phase noise of the VCO signal is substantially identical to the noise that the loop is aimed to correct via comparison to a low noise reference oscillator. It overcomes additional problems associated with traditional and prior art phase lock loops in terms of unwanted spurious signals, complexity, and cost.

Abstract: A cable distribution system with distributed architecture that can accommodate both digital and analog subscribers. Each home has at least one Room Interface Unit (RIU), one for each television. There is a local service module associated with a group of RIUs (e.g., one for every ten RIUs). There is also a local headend in the vicinity. The local headend has a block of integrated tuner/receiver/decoders that can be controlled to tune in a selected video channel. The selected video channels and a group of standard channels are multiplexed and sent to the local service modules where a group of programmable converters (one for each RIU) place the channel selected by its corresponding RIU at a predetermined frequency. Each of the RIUs associated with a particular local service module receive the corresponding channel. Depending upon whether the subscriber has subscribed to digital or analog service, they will have either a digital or an analog RIU.
