Probability, random variables, and random signal principles

the long version

"This edition maintains the original level and intent of the book as well as its audience of seniors or first-year graduate students. However, many improvements have been made. These include: sampling theory for random processes and how sampling forms the basis for discrete-time random processes. Other new material for digital signal processing (DSP) topics and a summary of DSP systems is included; new examples and problems have been added based on the use of MATLAB software. There are now 134 examples and nearly 900 homework problems; and other topics expanded or added include discussion of probability as a relative frequency, permutations, combinations, transformations of random variables, ergodicity of random processes, laws of large numbers, estimation, various inequalities, properties of impulses, and chapter-end summaries. This new material will prove most useful for students concerned with modern digital systems."--BOOK JACKET.
