Abstract
A method and system to process a spectrum of radio frequency (RF) signals. An analog to digital (A/D) converter is adapted to sample and digitize a spectrum of radio frequency (RF) signals. The spectrum of RF signals include a plurality of modulation techniques. The A/D converter is further adapted to sample the spectrum at a rate that is at least twice the frequency of the highest frequency signal that is contained within the spectrum. The digitized data stored in a memory device. A processor is adapted to process the digitized data.
Claims21
A system to process a spectrum of radio frequency (RF) signals, comprising:
- an analog to digital (A/D) converter, wherein the A/D converter is adapted to sample and digitize a spectrum of RF signals such that digitized data is generated, wherein the signals comprise a plurality of modulation techniques, wherein A/D converter is further adapted to sample the spectrum of RF signals at a rate that is at least twice the frequency of the highest frequency signal contained within the spectrum;
- at least one memory device adapted to store the digitized data;
- and
- a processor adapted to process the digitized data.
The system of claim 2, wherein the A/D convertor is a wide band A/D converter.
A method to process a spectrum of radio frequency (RF) signals, comprising:
- sampling and digitizing, by an analog to digital (A/D) converter, a spectrum of RF signals such that digitized data is generated, wherein the spectrum of RF signals comprise a plurality of modulation techniques, and wherein the A/D converter samples the spectrum of RF signals at a rate that is at least twice the highest frequency of the highest frequency signal contained within the spectrum;
- storing the digitized data on a memory device;
- and
- processing the digitized data using a processor.
