77.
An analog signal is a signal that uses the full range of a carrier wave characteristic to encode continuous data values. Analog signals are continuous in nature and thus they can represent any data value within a given range of values. they represent a varying quantity with respect to time.
78.
A digital signal can contain one of a finite number of possible values. This is in complete contrast to analog signals which contain continuous values. Digital signals can represent only a discrete set of values. Digital signals with two values is called a binary or logical signal.
79.
A communication channel consists of a sending device, a receiving device, and the transmission medium connecting them. It is used for communication or transmitting data between the two parties.
80.
The communication path that transport signal is called a transmission medium. These are material substances which can carry energy waves.
81.
The difference between a signal's maximum and minimum frequency is called the bandwidth. It represents the max amount of data that can be transferred.
82.
A composite signal is created by combining multiple simple signals. Two individual, separate signals join together to form a composite signal.
83.
Attenuation is the reduction in signal strength (amplitude) caused by interactions between the signal's energy and the transmission medium. It can occur in both digital and analog signals. It happens during long-distance transmission and leads to loss of data.
84.
The term distortion refers to changes to the data signal caused by interaction with the communication channel. It leads to changes in the original shape of the signal. Frequency, amplitude and phase distortion are some of the types of distortions.
85.
Twisted Pair cable is the most common transmission medium for phone and local area network (LAN) connections. These are created by twisting two separate conductor wires for improving electromagnetic compatibility. They are of two types: shielded and unshielded.
86. The coaxial cable contains a single copper conductor surrounded by a thick plastic insulator, a metallic shield, and a tough plastic outer wrapping. They are used to transmit radio signals and are commonly used for internet connections. A coaxial cable contains an inner conductor, surrounded by an insulating layer and is covered by outer insulating jackets.
