computing devices so that they may interact with each other. Below is a chart that shows the different types of communication media. Analog and Digital Data Transmission There are a number of differences between analog and digital transmission‚ and it is important to understand how conversions between analog and digital occur. Now with the digital age taking over‚ many people think that analog transmission methods are no longer used. This is a big misconception and certainly not true. To understand

communications satellites‚ and undersea telephone cables connected by switching centers‚ which allows any telephone in the world to communicate with any other. Originally a network of fixed-line analog telephone systems‚ the PSTN is now almost entirely digital in its core and includes mobile as well as fixed telephones. The technical operation of the PSTN utilises standards created by the ITU-T. These standards allow different networks in different countries to interconnect seamlessly. There is also a

High Speed Digital Hardware Design White Paper Issue: 01‚ 11th November 2002 Mick Grant‚ Design Engineer Abstract As system clock frequencies and rise times increase‚ signal integrity design considerations are becoming ever more important. Unfortunately many Digital Designers may not recognise the importance of signal integrity issues and problems may not be identified until it is too late. This paper presents the most common design issues affecting signal integrity in high-speed digital hardware

Difference between Analog and Digital Technologies: Analog and digital signals are used to transmit information‚ usually through electric signals. In both these technologies‚ the information‚ such as any audio or video‚ is transformed into electric signals. The difference between analog and digital technologies is that in analog technology‚ information is translated into electric pulses of varying amplitude. In digital technology‚ translation of information is into binary format (zero or one)

electronics and communication‚ I am interested in digital signal processing. The merging of Communications has had a profound influence on the way digital systems are organized. I was fascinated by the concept of digitalization‚ which virtually shrunk the globe and its omnipresent nature. This diverse nature of digital systems with its new avenues for research motivates me to be part of this exciting field. In this direction‚ I chose digital signal processing in my final year of B.

Four-Channel Temperature Monitor & Controller Description: The project entitled “Four-Channel Temperature Monitor & Controller” brings out basic idea behind monitoring the various parameters using an Analog to Digital Converter. Normally in an Analog digital converter there are eight channels the A/D converter used here is 0809. In which the selection of these channels can be done using their address lines A0‚ A1‚ A3. Methodology: Any analog received from another external hardware can be
