High Precision Event Timer. The High Precision Event Timer ( HPET) is a hardware timer available in modern x86-compatible personal computers. Compared to older types of timers available in the x86 architecture, HPET allows more efficient processing of highly timing-sensitive applications, such as multimedia playback and OS task switching.
The resolution of 960H depends on whether the equipment is PAL or NTSC based: 960H represents 960 x 576 (PAL) or 960 x 480 (NTSC) pixels. [29] 960H represents an increase in pixels of some 30% over standard D1 resolution, which is 720 x 576 pixels (PAL), or 720 x 480 pixels (NTSC). The increased resolution over D1 comes as a result of a longer ...
In electronic instrumentation and signal processing, a time-to-digital converter ( TDC) is a device for recognizing events and providing a digital representation of the time they occurred. For example, a TDC might output the time of arrival for each incoming pulse. Some applications wish to measure the time interval between two events rather ...
Timing synchronization function. Timing synchronization function (TSF) is specified in IEEE 802.11 wireless local area network (WLAN) standard to fulfill timing synchronization among users. A TSF keeps the timers for all stations in the same basic service set (BSS) synchronized. All stations shall maintain a local TSF timer.
555 timer IC. The 555 timer IC is an integrated circuit used in a variety of timer, delay, pulse generation, and oscillator applications. It is one of the most popular timing ICs due to its flexibility and price. Derivatives provide two ( 556) or four ( 558) timing circuits in one package. [ 2]
The Environmental Protection Agency is expected to propose restrictions on harmful “forever chemicals” in drinking water after finding they are dangerous in amounts so small as to be undetectable.
The temporal resolution is a resolution somewhat the 'time' dual to the 'space' resolution of an image. In a similar way, the sample rate is equivalent to the pixel pitch on a display screen, whereas the optical resolution of a display screen is equivalent to temporal uncertainty. Note that both this form of image space and time resolutions are ...
The Standard Television Interface Chip or STIC is a video encoder chip produced by General Instrument as AY-3-8900/AY-3-8900-1 and used on the Mattel Intellivision.. The chip provides all the display functions on the machine, and works as an internal timer.
