Analog and digital communication book pdf
Analog and Digital Communication - ADC Study Materials | PDF FREE DOWNLOADThe rapid expansion of digital communications, particularly in the fields of TV and mobile telephones does not overide the need for a clear understanding of analogue frequencies. Moreover, analogue technology will play an important role in communications well into the 21st century. Covering the principles behind analogue and digital communication systems, this book takes a less mathematical approach than is often found at this level. It begins with basic principles such as information systems, data compression and error detection before moving on to more advanced topics such as Pulse Code Modulation systems and digital microwave systems. Data protocols are also given so that the reader can gain a good understanding of more complex communication systems.

Data transmission also data communication or digital communications is the transfer of data a digital bitstream or a digitized analog signal  over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires , optical fibers , wireless communication channels, storage media and computer buses. The data are represented as an electromagnetic signal , such as an electrical voltage , radiowave , microwave , or infrared signal. Analog or analogue transmission is a transmission method of conveying voice, data, image, signal or video information using a continuous signal which varies in amplitude, phase, or some other property in proportion to that of a variable. The messages are either represented by a sequence of pulses by means of a line code baseband transmission , or by a limited set of continuously varying wave forms passband transmission , using a digital modulation method. The passband modulation and corresponding demodulation also known as detection is carried out by modem equipment.
