What is Digital Communication?
Digital communication is a branch of engineering that deals with the transmission and reception of information using digital signals. Digital signals are sequences of binary digits (0s and 1s) that represent data, such as text, images, audio, video, etc. Digital communication systems use various techniques to encode, modulate, transmit, demodulate, decode, compress, encrypt, decrypt, store, process, and display digital signals.
Digital communication has many applications in various fields, such as telecommunications, computer networks, wireless communications, satellite communications, radar systems, cryptography, multimedia systems, etc. Digital communication also enables many modern technologies and services that we use every day, such as mobile phones, internet, email, social media, streaming platforms, online gaming, etc.
Who is John Proakis?
John Proakis is a professor emeritus of electrical and computer engineering at Northeastern University in Boston, Massachusetts. He received his B.S. degree in electrical engineering from the University of Cincinnati in 1959, and his M.S. and Ph.D. degrees in electrical engineering from Northwestern University in 1961 and 1964, respectively. He has over 50 years of teaching and research experience in the fields of digital communication, signal processing, and wireless communication.
