The Signal Processing Technique in the Time-Domain Approach of Determining the Residual Error Terms of the Calibrated VNA

Abstract

Sophisticate mathematic computation is used when the residual error parameters are estimated employing time domain technique. This paper discuss the improved method of employing Window function before the inverse Fourier transform. At the same time, we find the curve of time domain will be out of the standard shape when the linear prediction of the measured signal section is too long, and some figures are offered to illustrate it.
