MPX Filter
MPX filter is a function found in analogue stereo FM broadcasting and personal monitor equipment, FM tuners and cassette decks. An MPX filter is, at least, a notch filter blocking the 19 kHz pilot tone, and possibly higher frequencies in the 23-53kHz and 63-75kHz bands. Broadcasting and personal monitors FM stereo broadcasts contain a ''pilot tone'' - a 19 kHz sinewave serving as a phase reference for decoding the stereophonic information. The system was developed jointly by Zenith and General Electric, and approved by the FCC in 1961. Normal monaural audio, the pilot tone and the double sideband stereophonic difference information are all mixed together into composite FM baseband signal extending to 53 kHz (stereo audio only) or 99 kHz (stereo audio plus an auxiliary subchannel, so-called ''SCA''). The process of encoding the difference signal into the 23-53kHz band via double-sideband carrier-suppressed amplitude modulation is an instance of multiplexing (hence the name '' ...

Multiplexing
In telecommunications and computer networking, multiplexing (sometimes contracted to muxing) is a method by which multiple analog or digital signals are combined into one signal over a shared medium. The aim is to share a scarce resource - a physical transmission medium. For example, in telecommunications, several telephone calls may be carried using one wire. Multiplexing originated in telegraphy in the 1870s, and is now widely applied in communications. In telephony, George Owen Squier is credited with the development of telephone carrier multiplexing in 1910. The multiplexed signal is transmitted over a communication channel such as a cable. The multiplexing divides the capacity of the communication channel into several logical channels, one for each message signal or data stream to be transferred. A reverse process, known as demultiplexing, extracts the original channels on the receiver end. A device that performs the multiplexing is called a multiplexer (MUX), and a dev ...

Multiplexer
In electronics, a multiplexer (or mux; spelled sometimes as multiplexor), also known as a data selector, is a device that selects between several analog or digital input signals and forwards the selected input to a single output line. The selection is directed by a separate set of digital inputs known as select lines. A multiplexer of 2^n inputs has n select lines, which are used to select which input line to send to the output. A multiplexer makes it possible for several input signals to share one device or resource, for example, one analog-to-digital converter or one communications transmission medium, instead of having one device per input signal. Multiplexers can also be used to implement Boolean functions of multiple variables. Conversely, a demultiplexer (or demux) is a device taking a single input and selecting signals of the output of the compatible mux, which is connected to the single input, and a shared selection line. A multiplexer is often used with a complement ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megapixel
In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest point in an all points addressable display device. In most digital display devices, pixels are the smallest element that can be manipulated through software. Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color imaging systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black. In some contexts (such as descriptions of camera sensors), ''pixel'' refers to a single scalar element of a multi-component representation (called a ''photosite'' in the camera sensor context, although ''sensel'' is sometimes used), while in yet other contexts (like MRI) it may refer to a set of component intensities for a spatial position.

Multi-Pointer X
Multi-pointer X (MPX) is a part of X input extension and previously a modification to the existing X.Org implementation of the X Window System. MPX provides multiple independent pointers at the windowing system level. These pointers are all connected to one computer. Unlike many other multi-pointer applications and toolkits, MPX allows many existing X11 applications to run unmodified, whilst still providing additional input features. For instance, multiple users can simultaneously operate different applications at the same time. Some applications do not work as expected due to limitations in the toolkits they use . The limitations are caused by the assumption that only one pointer exists. Window manager Combined with the proof of concept window manager MPWM, MPX provides extended features such as simultaneous movement or resizing of application windows, per pointer annotation over top of an application and restricted input support ( floor control). Applications that are aware of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MPX Microsoft Project Exchange File Format
MPX Microsoft Project File Exchange Format is a file format developed by Microsoft which was introduced with Microsoft Project 4.0 (1994) for sharing project data with other project management applications. It was adopted by other project management Project management is the process of leading the work of a team to achieve all project goals within the given constraints. This information is usually described in project documentation, created at the beginning of the development process. Th ... applications, such as Primavera Project Planner and Sciforma. Microsoft discontinued the ability to save in the MPX format with Microsoft Project 2000, but the ability to read the MPX format is supported up to Microsoft Project 2010.

Intel MPX
Intel MPX (Memory Protection Extensions) was a set of extensions to the x86 instruction set architecture. With compiler, runtime library and operating system support, Intel MPX claimed to enhance security to software by checking pointer references whose normal compile-time intentions are maliciously exploited at runtime due to buffer overflows. In practice, there have been too many flaws discovered in the design for it to be useful, and support has been deprecated or removed from most compilers and operating systems. Intel has listed MPX as removed in 2019 and onward hardware in section 2.5 of its Intel® 64 and IA-32 Architectures Software Developer's Manual Volume 1. Extensions Intel MPX introduces new bounds registers, and new instruction set extensions that operate on these registers. Additionally, there is a new set of "bound tables" that store bounds beyond what can fit in the bounds registers. MPX uses four new 128-bit bounds registers, BND0 to BND3, each storing a pair of ...

K-PEX 100
The K-Pex 100 (Kingston Portable Entertainment eXperience) is a portable media player produced by Kingston Technologies. It is capable of playing transcoded videos ( .mpx), viewing still images (.jpg), and playing music files (.mp3, .wma). It also comes with 2 games. It is a rebranded Cenix GMP-M6, which is from Korea. Production of the K-PEX has been discontinued. Supported formats The Kingston K-Pex-100 is capable of playing various formats of audio, video, picture, and game files. Audio formats MP3, WAV, WMA (protected), Ogg (Q10) Video formats WMV, ASF, MPEG 1 & 2, and AVI can be transcoded into the supported MPX format. The .mpx format is based on the mp4 format. It is unclear what codec it uses for both video and audio. The transcoded files are transcoded to the exact size of the screen to ensure minimum file size.

PowerPC G4
PowerPC G4 is a designation formerly used by Apple and Eyetech to describe a ''fourth generation'' of 32-bit PowerPC microprocessors. Apple has applied this name to various (though closely related) processor models from Freescale, a former part of Motorola. Motorola and Freescale's proper name of this family of processors is PowerPC 74xx. Macintosh computers such as the PowerBook G4 and iBook G4 laptops and the Power Mac G4 and Power Mac G4 Cube desktops all took their name from the processor. PowerPC G4 processors were also used in the eMac, first-generation Xserves, first-generation Mac Minis, and the iMac G4 before the introduction of the PowerPC 970. Apple completely phased out the G4 series for desktop models after it selected the 64-bit IBM-produced PowerPC 970 processor as the basis for its PowerPC G5 series. The last desktop model that used the G4 was the Mac Mini which now comes with an Apple M1 processor. The last portable to use the G4 was the iBook G4 but was replaced ...
