the minimum bandwidth required to transfer the information. The signal distributing is accomplished by deploying a pseudo-noise code which is not directly connected to the data. The pseudo-noise code is used as a modulation waveform to expand the baseband signal over a bandwidth much greater than the signal information bandwidth. At the receiver a reception synchronized to the code is used to demodulate the signal and collect the data. In the diagram above you can see what the information signal
Data Transmission The purpose of this report is to describe some common data transmission terminology. This paper will discuss various data transmission (communication) protocols and how they are used in data communication. Synchronous and Asynchronous: Asynchronous serial transmission is a technique used in serial RS232 communication. The data is framed by a series of control bits known as the start bit, stop bit(s), parity bits and error checking bits. A transmit clock signal is used to

A: outer plastic sheath B: copper screen C: inner dielectric insulator D: copper core There are two types of coaxial cables: 1. Thinnet 2. Thicknet Thinnet Also known as "Thin Ethernet" or Thinnet, 10BASE-2 is an IEEE standard for baseband Ethernet at 10MBps over thick coaxial cable. 10Base2 has a maximum distance of 185 meters. Thin Ethernet is five millimeters in diameter and used to connect machines up to 1,000 feet apart. Thinnet (thin Ethernet) is an incarnation of the Ethernet

However the most common definition of digital communication consider both passband and baseband as digital transmission. Data that is transmitted can either be in digital form, for example originating from a data sources like computer etc. or it can be in analog form such as a video/audio signal which is then digitized into a bit-stream by
Abstract The Physical Layer is the lowest layer of the Open Source Interconnect Model (OSI). It is the layer that deals with all the measurable, physical entities associated with the network. At this layer it is specified how much bandwidth (Baseband or Broadband) will be used in the transmission of data on the network. This layer also includes the physical topology (physical lay out) of the network such as: Bus, Star, Ring or Mesh. The Physical Layer includes these devices: Network Interface
Q1. What is the relationship between period and frequency? Period refers to the amount of time needed to complete 1 cycle and is expressed in seconds. Frequency is the number of cycles per second and is measured in Hertz(Hz) , or the rate of change with respect to time. Period and frequency are the inverse of each other, the mathematical representation of the relation is: Frequency = 1/T (period) Period = 1/F (frequency) Example: The period of a single cycle is 0.1 seconds, so to find the frequency
Synchronous and Asynchronous mode: In telecommunication signaling within a network or between networks, synchronous signals are those that occur at the same clock rate when all clocks are based on a single reference clock. Synchronous communication requires that each end of an exchange of communication respond in turn without initiating a new communication. An asynchronous signal is one that is transmitted at a different clock rate than another signal. Asynchronous operation also means that a process
Before the implementation of BlueTooth into cellular devices, cell phone users were either required to have a wired earpiece running to their phone, or use one of their hands to hold the phone to their ears. Bluetooth has become a vital part of corporate use because it allows for employees to excel in multitasking, making it one of the world’s most used wireless connection system. Cell phone manufacturers prefer BlueTooth to any other type of technology because of the
German courts The following is a case investigation of lawsuits between Apple Inc. and Samsung Electronics regarding the design of smartphones and tablet computers between them according to German courts. In July 2011, Apple sued Samsung for patent infringement, namely through items including the Samsung Galaxy Tab 10.1. Apple claims that Samsung infringed its patents in the Galaxy line of smartphones and tablets, arguing that Samsung copied the design and esthetics of Apple's ios range of devices
Xintec (Minasians, 2016). Further, it is worthy to note that the components of iPhone 5s and iPhone 6 are from differnt countries: accelerometer is from Bosch in Germany; audio chipsets and coded are outsourced for manufacturing in the United States; baseband processor are from Qualcomm in the U.S.; batteries are made in South Korea or China; cameras are from Sony in Japan, the FaceTime camera chip is from OmniVision in the U.S. or the TMSC in Taiwan; chipsets and processors are from South Korea and Taiwan
Introduction In this modernize world, internet and network are very vital and important not only for individuals but also for companies, organization, institution, etc. Because of this, it is very important to make use of as many network devices available. We need to study more or at least to have a glimpse of information about the networking devices before we choose or start using it. There are many networking device out there that able for us to study but the chosen device for this report are hub
The use of light as a communication media used in China Great Wall distance more than 7300 km with in 1 hour to sent signal from one tower to another. In the late 20th century optical communication took back in to the seat for its advantages over coaxial transport and other electrical communication system. In 1966, Kaw and Hockman proposed the idea of using optical fiber light wave communication and their prediction was data loss 20dB/km [12]. In late 1980s to 1990s, coherent detection communication
mobile solutions. The implementation of RF circuits on the nanoscale digital CMOS process with no or minimal process enhancements is one of the key obstacles limiting the complete single-chip integration of cellular radio functionality with digital baseband for mass production. The key challenges for the RF integration in nanoscale CMOS include non-linearity of devices and circuits, device mismatches, process parameter spread, and the increasing potential for self-interference that could be induced
broadcasting in stereo. The basic receiver design consists of the following components. An antenna is used to convert electro-magnetic waves into electrical oscillations. Amplifiers are used throughout the receiver to boost signal power at radio, baseband and intermediate frequencies. The core of the FM receiver, the discriminator, comes in various circuit forms and is used in detection and demodulation. Basically, its role is to extract the intelligence or message from the carrier wave. Another component
What makes sex so scandalous? Why is the American culture so ‘hush, hush’ about the friction in the sheets while the rest of the world exploits it? Regardless of what the world does, in general, this country desires to protect the youth from sex in television and radio. Some Americans feel furious when seeing or hearing sexual material and send complaints to the Federal Communications Commission (FCC). While others either support the questionable material or feel indifferent towards it. The
LOCAL AREA NETWORK (LAN) <>INTRODUCTION<> Local Area Network is a computer network connecting computers within a small area or places. LAN size is limited to a few kilometres. More than one LAN can be connected to one another by using telephone lines or through radio waves. LAN has higher data transfer rates. LAN is built in with inexpensive hardware such as Ethernet cables, network adapters and hubs. Special operating system is also be used to configure LAN. Microsoft Windows provide software
Searching documents using keywords is a very common practice. This practice of word-based information retrieval is affected by two complimentary problems. First is, we may get some relevant as well as some irrelevant search results if we use the keyword along with some possible meaning of the same for the search. Second is, if only the title keyword is used then some relevant text may miss out as some times the text related to that keyword doesn’t contain that rather contains some context of that
Analysis of Transaction Processing Systems It is the processing in which a system respond to a user’s command to carry out some operation to and fro. The request or command is called TRANSACTION, and the system carrying it out is called TRANSACTION PROCESSING SYSTEM e.g cash machines. Transaction processing systems are the systems working at a low level of any organizational structure being operated by data entry operators etc to collect and store data which is needed to be transported then
