This paper is intended to present a quantitative method of analysis of sampling measurement or conversion of time varying random signals. The analysis is developed by deriving a formula which gives the average information amount per unit time obtained through the sampling measurement of a Gaussian random signal. Considering the limiting case of the formula when the repetition frequency of the sampling measurement is increased extremely, the order of increase of the information amount vs.sampling frequency is examined and interpreted from physical points of view. Comparison between sampling and continuous measurement of the signals is also made in this paper. Using the formula the numerical values of the information amount obtained through the sampling measurement are calculated for several kinds of signal power spectra, and in connection with these examples some interesting phenomena are described.
