Birth and education George Feher (hungarian: György Fehér) was born in Bratislava, Czechoslovakia in 1924. Fehér is a hungarian name and his birth town, Pozsony in hungarian (Pressburg in german) was ceeded from Hungary 4 years before his birth. So Fehér was a hungarian jew.

Descrambler
In telecommunications, a scrambler is a device that transposes or inverts signals or otherwise encodes a message at the sender's side to make the message unintelligible at a receiver not equipped with an appropriately set descrambling device. Whereas encryption usually refers to operations carried out in the Digital data, digital domain, scrambling usually refers to operations carried out in the Analog transmission, analog domain. Scrambling is accomplished by the addition of components to the original signal or the changing of some important component of the original signal in order to make extraction of the original signal difficult. Examples of the latter might include removing or changing vertical or horizontal sync pulses in television signals; televisions will not be able to display a picture from such a signal. Some modern scramblers are actually encryption devices, the name remaining due to the similarities in use, as opposed to internal operation. In telecommunications and ...

The high commissioner for Palestine was the highest ranking authority representing the United Kingdom in the mandated territories of Palestine, and the high commissioner for Transjordan was the highest ranking authority representing the United Kingdom in Transjordan. These posts were always held simultaneously by a single individual after the high commissioner for Transjordan was established in 1928. The British representative to Amman was "responsible to the high commissioner in his role as representative of the mandatory power, but not in his capacity as head of the Palestine administration." They were based in Jerusalem. The office commenced on 1 July 1920, before the commencement of the Mandate on 29 September 1923, and replaced the British military occupation under the Occupied Enemy Territory Administration, which had operated in Palestine in 1917–1918. The office ceased with the expiration of the Mandate on 15 May 1948. When the office of high commissioner was vaca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telephone Tapping
Wiretapping, also known as wire tapping or telephone tapping, is the monitoring of telephone and Internet-based conversations by a third party, often by covert means. The wire tap received its name because, historically, the monitoring connection was an actual electrical tap on an analog telephone or telegraph line. Legal wiretapping by a government agency is also called lawful interception. Passive wiretapping monitors or records the traffic, while active wiretapping alters or otherwise affects it. Legal status Lawful interception is officially strictly controlled in many countries to safeguard privacy; this is the case in all liberal democracies. In theory, telephone tapping often needs to be authorized by a court, and is again in theory, normally only approved when evidence shows it is not possible to detect criminal or subversive activity in less intrusive ways. Oftentimes, the law and regulations require that the crime investigated must be at least of a certain sever ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oscilloscope
An oscilloscope (formerly known as an oscillograph, informally scope or O-scope) is a type of electronic test instrument that graphically displays varying voltages of one or more signals as a function of time. Their main purpose is capturing information on electrical signals for debugging, analysis, or characterization. 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, engineering, biomedical, 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 ignition system or to display th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franz Ollendorff
Franz Heinrich Ollendorff ( or חיים אולנדורף; May 15, 1900 – December 9, 1981) was an Israeli physicist. Biography Franz Heinrich (Haim) Ollendorf was born in Berlin.
