The IBM 1711 Data Converter was part of the IBM 1710 process control computer.
 The 1711 contained an analog-to-digital converter that accepted signals from the IBM 1712 Multiplexer and Terminal Unit that were between -50 millivolts and +50 millivolts and converted them into signed, four decimal digit numbers that were stored in the 1710s core memory.
A digital-to-digital converter is a device to convert from one type of digital data to another type of digital data.
 For example, a Digital-to-Digital (DD) Converter may consist of a sample rate or bit depth converter.
 It may also convert one form of digital data to another.
 For example, Binary data to Gray data.
Mau-Chung Frank Chang (, born February 20, 1951) is Distinguished Professor and the Chairman of Electrical Engineering department at the University of California, Los Angeles, where he conducts research and teaching on RF CMOS design, high speed integrated circuit design, data converter, and mixed-signal circuit designs.
 He is the Director of the UCLA High Speed Electronics Laboratory.
A VGA box is a video converter that convert common analog video standards such as S-Video and component video to VGA format.
 Some VGA boxes include audio outputs for connecting to computer speakers. Others models include devices that convert VGA signals to composite, S-video or component video, as well as SCART in Europe.
 A VGA to HDMI converter, digitizes incoming analog VGA signal and upscales to 720P or 1080P HDTV resolutions and enables an analog VGA video source to be displayed on a HDTV via HDMI connection.
 The scaling engine ensures the VGA output fits the full HDTV screen with no image shifting or alignment issues
Analog Devices, Inc., also known as ADI or Analog, is an American multinational semiconductor company specializing in data conversion and signal processing technology, headquartered in Norwood, Massachusetts.
 In 2012, Analog Devices led the worldwide data converter market with a 48.5% share, according to analyst firm Databeans.
The IBM 1712 Multiplexer and Terminal Unit was part of the IBM 1710 process control computer.
 The Terminal Unit provided the physical connections between factory wiring and the computer.
 The 1712 could support up to 300 separate wire pairs.
 Signal types supported included analog input, analog output, contact sense, contact operate, process branch indicators and process interrupts.
 Special terminal blocks supported thermocouple inputs.
 The Multiplexer selects which signal was connected to the IBM 1711 Data Converter.
The Martin AN/TSQ-8 Coordinate Data Set was a Project Nike CCCS system for converting data between Army Air Defense Command Posts (AADCP) and Integrated Fire Control sites for missile Launch Areas.
 The AN/TSQ-8 in the Firing Unit Integration Facility (FUIF) was first installed for each Launch Area controlled from a Martin AN/FSG-1 Antiaircraft Defense System and then later for other Nike CCCS.
 The system included a "data converter, range computer, summing amplifier, status relay panel, status control panel, problem unit, [and] power control panel".
The digital television transition, also called the digital switchover, the analog switch-off (ASO), or the analog shutdown, is the process in which analog television broadcasting is converted to and replaced by digital television.
 This primarily involves the conversion of analog terrestrial television to digital terrestrial.
 However, it also involves analog cable conversion to digital cable, as well as analog to digital satellite television.
 This is an involved process because the existing analog television receivers owned by viewers cannot receive digital broadcasts; viewers must either purchase new digital TV's or converter boxes which change the digital signal to an analog signal which can be viewed on the old TV.
Analog Dialogue is a technical magazine published by Analog Devices (ADI).
 It is a forum for the exchange of information related to circuits, systems, and software for real-world signal processing.
 It discusses products, applications, technology, and techniques for analog, digital, and mixed-signal processing, serving as a gateway to ADI’s technology.
 "Analog Dialogue" is published monthly on the Web, and featured technical articles are compiled in quarterly print editions.
 The headquarters of the magazine is in Norwood, Massachusetts.
The current editor-in-chief is Bernhard Siegel.
A cable converter box or television converter box is an electronic tuning device that transposes/converts any of the available channels from a cable television service to an analog RF signal on a single channel, usually VHF channel 3 or 4, or to a different output for digital televisions such as HDMI.
 The device allows a television set that is not “cable ready” to receive cable channels.
 While later televisions were "cable ready" with a standard converter built-in, the existence of premium television (aka pay per view) and the advent of digital cable have continued the need for various forms of these devices for cable television reception.
 While not an explicit part of signal conversion, many cable converter boxes include forms of descrambling to manage carrier-controlled access restriction to various channels.
