I have heard of three books of Proakis namely Communication System Engineering, Digital Signal Processing and Digital Communications. I love the way he writes and would like to read about continuous/analog signals and systems by the same writer. Some of it has been dealt with in his book 'Communication System Engineering' namely Fourier Series and Fourier Transform. I want to read other continuous time topics like Laplace transform by the same author.
Is there any book by Proakis available which fully deals with continuous time signals and systems?
