NumberTitleIssue Date
5808895Method and apparatus for low signal to noise ratio instantaneous phase measurement
The system and method of the present invention generates high resolution phase measurements without the high processing and memory overhead requirements found in prior art circuits and methods. Each signal sample (of N samples) is divided further into J s...
