Title: well organized, right amount of depth
Review: Stallings went a bit into signal theory and some people don't like it. There is no book that can satisfy everyone, or answer everyone's every question. To me, it is a good technical book as long as (1) it justifies its price by having a reasonable amount of content, cohesive with the title and editorial reviews. (2) It has a good balance between rigor and ease of reading. In my opinion, this book satisfies both of the above, and it happens that I like the fact that it goes into signal theory. It is a good textbook for student who wants a short cut to communication fields without too much pure classroom math or EE stuffs, although practising engineers may not even need that limited amount of math.
