The origins of this book lie in our earlier book Random Processes: A Math-
ematical Approach for Engineers (Prentice Hall, 1986). This book began as
a second edition to the earlier book and the basic goal remains unchanged
– to introduce the fundamental ideas and mechanics of random processes to
engineers in a way that accurately reflects the underlying mathematics, but
does not require an extensive mathematical background and does not belabor
detailed general proofs when simple cases suffice to get the basic ideas
across.
