Approach to the Digital Signal Processing in Noiseproof Impedance Measuring Analyzers

Abstract

Specific features of the application of digital signal processing in noiseproof broadband impedance measuring analyzers are considered. It is shown that the use solely of the procedure of digital signal filtering is inefficient in this case. We propose to form an array of integrated weighted values of the signal instead of the array of its instantaneous values, thus realizing the procedure of preliminary analog filtering of the signal prior to the stage of analog-to-digital conversion.
