最近发展的各种调制方法，如PCM和PPM，交换带宽的信噪比，加强了对一般通信理论的兴趣。这样一个理论的基础包含在Nyquist [1]和Hartley [2]关于这个问题的重要论文中。在本文中，我们将扩展理论，包括一些新的因素，特别是在信道中的噪声的影响，和储蓄可能由于原始消息的统计结构，并由于信息的最终目的地的性质。
The recent development of various methods of modulation such as PCM and PPM which exchange bandwidth for signal-to-noise ratio has intensified the interest in a general theory of communication. A basis for such a theory is contained in the important papers of Nyquist1and Hartley2on this subject. In the present paper we will extend the theory to include a number of new factors, in particular the effect of noise in the channel, and the savings possible due to the statistical structure of the original message and due to the nature of the final destination of the information.
