Became a nearly ubiquitous analog computer display connector after first being introduced with IBM x86 machines. Older VGA connectors were DE-9 (9-pin). The modern DE-15 connector can carry Display Data Channel to allow the monitor to communicate with the graphics card, and optionally vice versa. [1] Being replaced by DVI from 1999 onward. DB13W3
Data Carrier Detect (DCD) or Carrier Detect (CD) is a control signal present inside an RS-232 serial communications cable that goes between a computer and another device, such as a modem. This signal is a simple "high/low" status bit that is sent from a data communications equipment (DCE) to a data terminal equipment (DTE), i.e., from the modem ...
Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
RCA connectors, also known as phono connectors or phono plugs, used for analog or digital audio or analog video; Speakon connectors by Neutrik for loudspeakers; Phone connector also known as tip-ring-sleeve (TRS) or tip-sleeve plug, phone plug, jack plug, mini-jack, and mini-stereo. This includes the original 6.35mm (quarter inch) jack and the ...
Cable telephony is a form of digital telephony over cable TV type networks. A telephone interface installed at the customer's premises converting analog signals from the customer's in-home wiring to a digital signal, which is then sent over the cable connection to the company's Cable television headend switching center.
A composite monitor or composite video monitor is any analog video display that receives input in the form of an analog composite video signal to a defined specification. [1] A composite video signal encodes all information on a single conductor; a composite cable has a single live conductor plus earth.
In addition to digital, some DVI connectors also have pins that pass an analog signal, which can be used to connect an analog monitor. The analog pins are the four that surround the flat blade on a DVI-I or DVI-A connector. A VGA monitor, for example, can be connected to a video source with DVI-I through the use of a passive adapter. Since the ...
ADCs are required in digital signal processing systems that process, store, or transport virtually any analog signal in digital form. TV tuner cards, for example, use fast video analog-to-digital converters. Slow on-chip 8-, 10-, 12-, or 16-bit analog-to-digital converters are common in microcontrollers.
