SyntheSys Research
SyntheSys Research was a Silicon Valley test equipment company that existed from 1989 to 2010, located in Menlo Park, California. The company was founded by Tom and Jim Waschura, with technical help from other ex-Ampex employees Rob Verity and Kirk Handley, and early marketing help from Bob Haya who was Tom and Jim's roommate. The first product was a 160 Mbit/s bit error rate tester (BERT) called the BitAlyzer 160 that debuted in 1989. The company patented key technologies used in modern signal integrity test; notably ''Error Location Analysis'' and statistically deep eye-diagramming integrated with BERT measurement called ''BERTScope''. The company was the first to combine Jitter sources in its test signal generators to permit popular ''Stressed-Eye'' testing. The company developed many products over its 21-year span, including specialty products for disk-drive, television, high-definition television, optical, telecommunications, and computer applications. In 2010, SyntheSys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eye Pattern
In telecommunication, an eye pattern, also known as an eye diagram, is an oscilloscope display in which a digital signal from a receiver is repetitively sampled and applied to the vertical input, while the data rate is used to trigger the horizontal sweep. It is so called because, for several types of coding, the pattern looks like a series of eyes between a pair of rails. It is a tool for the evaluation of the combined effects of channel noise, dispersion and intersymbol interference on the performance of a baseband pulse-transmission system. The technique was first used with the WWII SIGSALY secure speech transmission system. From a mathematical perspective, an eye pattern is a visualization of the probability density function (PDF) of the signal, modulo the unit interval (UI). In other words, it shows the probability of the signal being at each possible voltage across the duration of the UI. Typically a color ramp is applied to the PDF in order to make small brightness dif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oscilloscope
An oscilloscope (informally a scope) is a type of electronic test instrument that graphically displays varying electrical voltages as a two-dimensional plot of one or more signals as a function of time. The main purposes are to display repetitive or single waveforms on the screen that would otherwise occur too briefly to be perceived by the human eye. The displayed waveform can then be analyzed for properties such as amplitude, frequency, rise time, time interval, distortion, and others. Originally, calculation of these values required manually measuring the waveform against the scales built into the screen of the instrument. Modern digital instruments may calculate and display these properties directly. Oscilloscopes are used in the sciences, medicine, engineering, automotive and the telecommunications industry. General-purpose instruments are used for maintenance of electronic equipment and laboratory work. Special-purpose oscilloscopes may be used to analyze an automotive ign ...

Advent International
Advent International is a global private equity firm focused on buyouts of companies in Western and Central Europe, North America, Latin America and Asia. The firm focuses on international buyouts, growth and strategic restructuring in five core sectors. Since its inception in 1984, Advent has invested $56 billion in private equity capital and, through its buyout programs, has completed more than 375 transactions in 42 countries. Advent operates from 14 offices in 11 countries, with affiliates in additional countries, and employs over 240 investment professionals. History Advent is a Boston, Massachusetts spin-out from TA Associates by Peter Brooke. Brooke had founded TA Associates in 1968 after having expanded the venture capital operations of TA's parent Tucker Anthony & R.L. Day. In 1985, Advent raised its first fund – a $14 million corporate venture capital program for Nabisco. In 1987, the firm raised the $225 million International Network Fund, its first institutio ...

Dot-com Bubble
The dot-com bubble (dot-com boom, tech bubble, or the Internet bubble) was a stock market bubble in the late 1990s, a period of massive growth in the use and adoption of the Internet. Between 1995 and its peak in March 2000, the Nasdaq Composite stock market index rose 400%, only to fall 78% from its peak by October 2002, giving up all its gains during the bubble. During the dot-com crash, many online shopping companies, such as Pets.com, Webvan, and Boo.com, as well as several communication companies, such as Worldcom, NorthPoint Communications, and Global Crossing, failed and shut down. Some companies that survived, such as Amazon, lost large portions of their market capitalization, with Cisco Systems alone losing 80% of its stock value. Background Historically, the dot-com boom can be seen as similar to a number of other technology-inspired booms of the past including railroads in the 1840s, automobiles in the early 20th century, radio in the 1920s, television in the 19 ...

National Association Of Broadcasters
The National Association of Broadcasters (NAB) is a trade association and lobby group representing the interests of commercial and non-commercial over-the-air radio and television broadcasters in the United States. The NAB represents more than 8,300 terrestrial radio and television stations as well as broadcast networks. As of 2022, the president and CEO of the NAB is Curtis LeGeyt. Founding The NAB was founded as the National Association of Radio Broadcasters (NARB) in April 1923 at the Drake Hotel in Chicago. The association's founder and first president was Eugene F. McDonald Jr., who also launched the Zenith corporation. In 1951 it changed its name to the National Association of Radio and Television Broadcasters (NARTB) to include the television industry. In 1958 it adopted its current name, "National Association of Broadcasters". Commercial radio The NAB worked to establish a commercial radio system in the United States. The system was set up in August 1928 with th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Forward Error Correction
In computing, telecommunication, information theory, and coding theory, an error correction code, sometimes error correcting code, (ECC) is used for controlling errors in data over unreliable or noisy communication channels. The central idea is the sender encodes the message with redundant information in the form of an ECC. The redundancy allows the receiver to detect a limited number of errors that may occur anywhere in the message, and often to correct these errors without retransmission. The American mathematician Richard Hamming pioneered this field in the 1940s and invented the first error-correcting code in 1950: the Hamming (7,4) code. ECC contrasts with error detection in that errors that are encountered can be corrected, not simply detected. The advantage is that a system using ECC does not require a reverse channel to request retransmission of data when an error occurs. The downside is that there is a fixed overhead that is added to the message, thereby requiring a h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
