In digital signal processing, a digital down-converter ( DDC) converts a digitized, band-limited signal to a lower frequency signal at a lower sampling rate in order to simplify the subsequent radio stages. The process can preserve all the information in the frequency band of interest of the original signal. The input and output signals can be ...
Display Data Channel. 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.
Direct digital control is the automated control of a condition or process by a digital device (computer). [1] [2] Direct digital control takes a centralized network-oriented approach. All instrumentation is gathered by various analog and digital converters which use the network to transport these signals to the central controller.
Monitor Control Command Set or MCCS is a computer standard developed by Video Electronics Standards Association (VESA). It defines a binary protocol for controlling the properties of computer monitors from a host device such as PC, set-top box, etc. MCCS requires a bidirectional communication protocol like Display Data Channel between host and ...
Prefix code. A prefix code is a type of code system distinguished by its possession of the "prefix property", which requires that there is no whole code word in the system that is a prefix (initial segment) of any other code word in the system. It is trivially true for fixed-length codes, so only a point of consideration for variable-length codes .
The Dewey Decimal Classification (DDC) is structured around ten main classes covering the entire world of knowledge; each main class is further structured into ten hierarchical divisions, each having ten divisions of increasing specificity. [1] As a system of library classification the DDC is "arranged by discipline, not subject", so a topic ...
In the AHM 780 specification, the two-character numeric-only codes are sent in the DL and EDL elements along with the time assigned to each code (e.g. DL31/62/0005/0015 showing reason 31 for 5 mins and reason 62 for 15 minutes), and the three-character alphanumeric codes are sent in the DLA element (e.g. DLA31C/62A// showing subreason C for ...
This class of status code indicates the client must take additional action to complete the request. Many of these status codes are used in URL redirection. A user agent may carry out the additional action with no user interaction only if the method used in the second request is GET or HEAD. A user agent may automatically redirect a request.
