Comparative analysis among frequency sampling algorithm applied in microwave measurements

This paper presents a comparative analysis between five algorithms. The goal of the algorithms was to reduce the acquisition time for high frequency measurements using Vector Network Analyzer. The proposed algorithms were developed by the authors and in this paper the accuracy and the execution time will be analyzed. The results will be presented in terms of information consistency and dynamic behavior. Finally, a classification between the five proposed algorithms using a key performance indicator will emphasize only one algorithm with high performances regarding the significant number of frequencies reduction, the decreasing of computation effort keeping the accuracy and the consistency of the initial device response.
