This chapter discusses transmission systems. We
will emphasize electromagnetic, typically point-to-point, and
instantaneous communications. Thus we will not
consider mass media such as books and newspapers or radio and
the popular sense. It is often difficult to separate the "system" from
media used because in modern transmissions the arriving content often
through many channels at many rates, which can differ each time the
is transmitted and retransmitted. First we will consider
several of the basic terms of transmission including
noise, bandwidth, frequency, and analog and digital transmission. This
is followed by an explanation of modulation and multiplexing techniques
both digital and analog transmission. After an overview of networks and
techniques, we will briefly introduce the major transmission systems.
we will compare various attributes of these systems.
