3-1 Measures of Random Syntactic Information Shannon Theory of Information Key point: 1. Information is something that can be used to remove uncertainty 2. The amount of information can then be measured by the amount of uncertainty it removed. 3. In the cases of communications only waveform is concerned while meaning and value are ignored 4. Uncertainty and thus information are statistic in nature and statistical mathematics is enough.3-1 Measures of Random Syntactic Information Shannon Theory of Information 2.
