TAILIEUCHUNG - Digital Communication Systems

Reference subjects of digital information in English and fully understandable. This book was written to be a textbook for seniors or first - year graduate students interested in electrical communication systems. The book departs from the usual formata in two major respects. First, the text does not cover analog or pulse modulation systems. | y DIGITAL COMMUNICATION SYSTEMS PEYTON Z. PEEBLES JR.
