Today's increased use of digital sound and video makes data compression crucial to computer technology because of its vast storge and transmission requirements. The question in many applications is not whenter to compress data, but wgat compression method to apply.

Adam Drozdek's Elements of Data Compression presents the topic at a level that is useful for students. The author uses elementarylevel reppresentative metholds of text,audio,and video compression. Drozdek pressnts these metholds with pseudocode, tables,diagrams,and many worked-out exaples,and employs commonly used techniques that build upon the mathematics students have been exposed to in earlier courses. Where students are likely to need assistance, the author provide extensive auxiliary material on mathematical topics,including some basic facts about matrices,probability distributions, and Fourier analysis.
