Key Characteristics of Hartley’s Law
Information Content
At its core, Hartley’s Law revolves around the concept of information content. This term refers to the amount of data or information that can be communicated using a set of symbols. In simple terms, it’s about quantifying information. The more diverse and numerous the symbols or choices, the greater the information content transmitted. This idea forms the backbone of understanding complexities in communication and data processing systems.
Symbol Possibilities
The “symbols” in Hartley’s Law may range from characters in written text to different signals in a telecommunication system. The number of symbols or choices available in a given communication scenario significantly impacts the volume of information that can be communicated. More symbols equate to a higher potential for transmitting intricate and nuanced information.
