Modulation, Detection and Coding
Sale Price: $14.95  |
DescriptionTelecommunications constitute an increasingly important part of human society. In some ways, they are a foundation on which industrial countries rely. Telecommunications play in numerous areas including, banking, air traffic control, medicine, digital and voice communications. More and more people need to understand the foundations of modern telecommunications.The purpose of this book is to give an introduction to coding and modulation methods as well as other signal processing within modern telecom-munica-tions, using basic starting points. The principal topics are source coding, channel coding, modulation and detection. Adaptive channel equalisers and adaptive antennas, which are important parts of the detection process in many systems, are also covered and there are sections about link budget, sychronisation, together with codes and detectors for CDMA. The aim is to give the reader an understanding of the basic functions in telecommunication systems and the methods that are used for the analysis of a complete system.Telecommunications is a field which develops quickly. An understanding of analysing methods which goes beyond simply an understanding of the results of the analysis is valuable knowledge - knowledge that will remain relevant over time and which will aid in understanding new developments as they arise.This text contains theory, fully solved examples, exercises with answers and a short presentation of some communication systems. Basic knowledge in signal processing and probability theory is a necessity to acquire the material. The book is intended for courses on at least the master level but can also be used for self study. |

Automatic Modulation Recognition of Communication Signals
List Price: |
DescriptionAutomatic modulation recognition is a rapidly evolving area of signal analysis. In recent years, interest from the academic and military research institutes has focused around the research and development of modulation recognition algorithms. Any communication intelligence (COMINT) system comprises three main blocks: receiver front-end, modulation recogniser and output stage. Considerable work has been done in the area of receiver front-ends. The work at the output stage is concerned with information extraction, recording and exploitation and begins with signal demodulation, that requires accurate knowledge about the signal modulation type. There are, however, two main reasons for knowing the current modulation type of a signal; to preserve the signal information content and to decide upon the suitable counter action, such as jamming. Automatic Modulation Recognition of Communications Signals describes in depth this modulation recognition process. Drawing on several years of research, the authors provide a critical review of automatic modulation recognition. This includes techniques for recognising digitally modulated signals. The book also gives comprehensive treatment of using artificial neural networks for recognising modulation types. Automatic Modulation Recognition of Communications Signals is the first comprehensive book on automatic modulation recognition. It is essential reading for researchers and practising engineers in the field. It is also a valuable text for an advanced course on the subject. |

Analogue and Digital Communication Techniques
List Price: |
DescriptionThe 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. 'Analogue and Digital Communication Techniques' has been designed for students studying HND electronic communication courses but will also be useful to junior undergraduates on similar courses. Some knowledge of basic elctronics is assumed. |

TV Digital Optical Coax to Analog Stereo RCA Audio Converter Adapter 24Bit/192KHz, Includes NEW 6ft Optical Cable
List Price: |
DescriptionNEW Dynamic Audioworks DAC-2016 V2.0 24Bit / 192KHz Digital to Analog Audio Converter. The new DAC-2016 V2.0 Digital to Analog Audio converter box takes your coaxial or optical (S/PDIF or TOSLink) digital audio source and converts it to standard analog left/right audio, available for connection to an external device such as an amplifier or recording deck via standard RCA-style jacks. Now you can connect the digital audio output of your new TV to your stereo receiver, amplifier etc. Which most probably sounds better than any newer stereo with digital inputs. How it works. Simply run a short extension cable from an available digital audio output jack on your digital source device to the same type digital input on the DAC-2016 V2.0 converter then hook up your analog RCA-style left and right cables to the converter's analog RCA audio outputs and power up the converter. Select either Optical or Coax input via selector switch provided on the input side. Features: Features

Menotek Digital Audio To Analog Audio Converter
List Price: |
DescriptionHow It Works - A coaxial or optical audio output on your digital audio source connects into the input on the Digital to Analog Decoder. Just plug in either a Coaxial (spdif) cable or a Toslink (optical) cable to the input side. The Decoder is connected to the included power supply. Analog RCA (Red and White RCA Cables) connectors on the Decoder output L/R analog audio to your stereo or input of your device. This type of device is also know as a D to A converter. Please note that Cables are not Included: Installation is easy Simply run a short extension cable from an available digital audio output jack on your digital source device to the same type of digital input on the Converter. Then hook up your analog RCA-style left and right (red white) cables to the Converter's analog RCA jack outputs and plug in the converter and power up all equipment. That's it your done! Package Includes: (1) Digital to Analog Audio Converter (1) 12V DC Power Supply (1) Instruction Sheet Please note installation cables are not included. Note: This a one way directional digital to analog converter. PLEASE READ ------ Questions and Answers Q. Will this device convert Dolby Digital? A. No it will not convert Dolby Digital but on a lot of products you can change the settings. Let me explain. The most common problem we have seen is a change in setting on your device your trying to decode. As advertised this device converts LPCM is Linear Pulse Code Modulation, which is a method of encoding audio information digitally. Sometimes we have seen that customer have their systems set to Dolby Digital. This setting must be changed on the device your trying to convert. Most of DVD players and other devices support LPCM or other setting. You need to get into the menu of the device and adjust Dolby Digital to LPCM or other by using Remote control in most cases.
