# Athanasios Papoulis

**Athanasios Papoulis**(1921 –April 25 2002 ) was a Greek Americanengineer and appliedmathematician .**Life**He was born in

Greece in 1921 and graduated fromNational Technical University of Athens .**tudies**He contributed in the areas of

signal processing , communications, and signal andsystem theory . His classic book "Probability, Random Variables, and Stochastic Processes" is used as a textbook in many graduate-level probability courses inelectrical engineering departments all over the world. The book is widely used due to its balance between rigor and intuition. Hence, by staying away from complete mathematical rigor while emphasizing the physical and engineering interpretations ofprobability , his book gained wide popularity. He is one of the pioneers in the field ofstochastic process es.**Theory**Athanasios Papoulis specialised in engineering mathmatics, as those he coverd in his work "Probability, Random Variables, and Stochastic Processes" which covers probability, statistics, and estimation in the application of these fields to modern engineering problems. Papoulis also taught and developed subjects such as

stochastic simulation , mean square estimation, likelihood tests, maximum entropy methods,Monte Carlo method , spectral representations and estimation,sampling theory ,bispectrum and system identification,cyclostationary process es, deterministic signals in noise (part of deterministic systems anddynamical system studies),wave optics and the Wiener andKalman filter s.**ee also***Alexander Poularikas
