Abstract : The static and dynamic characteristics of digital measurement were first discussed and a comparison between digital measurements and analog measurement was then made on the basis of information theory. The comparison indicated that analog and digital measurements are not directly comparable even if related to the same information. It was shown that both types of measurement have their advantages and disadvantages for various applications. The maximum channel capacity in bits per second, in relations to the various parameters involved, was estimated and presented in diagrams. Some sources of uncertainty owing to less then perfect time-measuring precision were discussed. (Author)
