Analog to information converter

A method of identifying a spectrum and extracting features thereof for RF signals in an ultra-wide bandwidth;

• said method comprising the steps of
• a. obtaining said RF signal to be analyzed;
• b. high-pass filtering said obtained signal;
• c. digitizing said high filtered signal;
• d. analyzing said digitized signal;
• wherein said method further comprises a step of spectrum compressing (SC) further comprising splitting said high pass filtered signal into two channels;
• Phase true-time delay modulating (shifting) said signal within one of said channels.

A linear-analog-to information converter of an RF signal:

• said converter comprising:
• a. a linear spectrum compression (LSC) unit;
• b. two digitizers configured for sampling obtained original and modulated signals;
• c. a digital signal processing unit;
• wherein said LSC unit further comprises a splitter configured to split a high pass filtered signal to two channels, phase true-time delay line disposed in one of said channels.

A digital analog-to information converter of an RF signal:

• said converter comprising:
• a. two digitizers configured for sampling obtained signal at two specifically tuned sampling rates;
• b. a digital signal processing unit;
• wherein said digital signal processing unit is configured for digital Doppler generator processing characterized by predetermined sampling rates, a decimation procedure, Fast Fourier Transformation and a predetermined normalization of the frequency spectrum.
