❴Read❵ ➪ Digital Transmission of Information Author Richard E. Blahut – Tyrakel.de Digital transmission Digital transmission offers an advantage with regard to the acceptable signal to noise ratio SNR at the optical receiver Digital communications systems can tolerate large amounts Digital transmission Digital transmission offers an advantage with regard to the acceptable signal to noise ratio SNR at the optical receiver Digital communications systems can tolerate large amounts of signal loss and dispersion without impairing the ability of the receiver to distinguish a binary from a binary Digital signalling also reduces the effects that optical source nonlinearities and temperature Analog and Digital Transmission Technology Digital Transmission Digital transmission is quite different from analog transmission For one thing the signal is much simpler Rather than being a continuously variable waveform it is a series of discrete pulses representing one bits and zero bits see Figure Each computer uses a coding scheme called a collating sequence that defines what combinations of ones Explain advantages and disadvantages of digital Advantages of digital transmission Immunity to transmission noise and interference Regenerative of the coded signal along the transmission path is possible Communication can be kept “private” and “secured” through the use of encryption It is possible to use a uniform format for different kinds of baseband signals Lecture Transmission of Digital Signal I Lecture Transmi.
