The transfer of data from one point to another is known as digital
communication. Optical fibers, storage media, computer buses, wireless
communication channels and copper wires are a few types of channels used
in digital communications. The data in digital communication is
represented as an electrical voltage, microwave, radiowave and infrared
signal. Synchronous and asynchronous transmissions are the two types of
data communication. The transmission speeds at both the sending and
receiving end of the transmission are synchronized in synchronous
transmission by using clock signals. Asynchronous serial communication
uses start and stop bits to signify the beginning and end of a
transmission. Digital communications is an upcoming field of science
that has undergone rapid development over the past few decades. Some of
the diverse topics covered herein address the varied concepts and
applications that fall under this category. Scientists and students
actively engaged in this field will find this book full of crucial and
unexplored concepts.
