What Is The Meaning Of ADF?
The term ADF has two different meanings: in the terms of printer and aviation respectively. Both meanings can be explained clearly in the following points:
ADF In Printer: The term ADF in the printer is an acronym that stands for “Automatic Document Feeder”. It is a feature in printers, photocopies, fax machines or scanners wherein a stack of paper put into a machine and is then automatically fed through it, permitting the user to print, scan or copy without having to individually place each page into the machine.
There are usually two types of ADF’s that are capable of duplex scanning namely, RADF(Reverse Automatic Document Feeders) and DADF (Duplexing Automatic Document Feeders).
ADF In Aviation: The expression ADF in aviation is an acronym that stands for “Automatic Direction Finding”. It is an electricity-based aid used for the navigation that recognizes the relative bearing of an aircraft from a radio beacon transmitting in the MF or LF bandwidth, such as a Non-Directional Beam or trading radio transmitting station.
Undoubtedly, ADF constitutes of a loop aerial that is turned physically or electronically and also notices the direction of the least reception from the beacon relative to the aircraft direction.
