,Data—Its Representation and Manipulation,oncept—number systems. The number systems considered are those common ones of “normal binary representation,” negabinary, and Gray coding. We also introduce a less well known “mixed-radix system,” based on the factorials. This representation will be of use to us later on when we look at combinatorics.发现 发表于 2025-3-30 14:04:08

Source Encoding, and appropriately model the data source. Is it English text? A Markov source? Facsimile? Each source is unique and so are its output statistics. There is often great opportunity to remove redundancy from a source by using simple encoding methods and doing so may result in an appreciable savings in bits sent.
