(ADC) - Element that converts analog input to digital format.
This is an electronic device that converts a signal from an analog signal into a digital signal. Analog signals can come from sources such as a microphone or a telephone line. The signal is changed to digital so that it can be processed by the computer.
A component which samples incoming electrical signal at very short, regular intervals and generates a stream of numbers that are equivalent to the voltage received at each interval. (See "Digital To Analog Converter")
An electronic circuit that changes continuously variable analog signals into discrete numerical digital signals (bits). The common abbreviation is A/D.
In a narrow sense: A device (usually, a micro-chip) which transforms a signal from analog form to digital form. This is done by taking samples of the analog signal at regular intervals. Each analog sample value is then quantized into a binary code. In a wider sense: Device performing all functions, necessary to convert analog video signals to a specified digital interface format, in particular sampling frequency genlocking, video signal pre-filtering, black level clamping, sync code word insertion, and even parallel-to-serial conversion.
This is the process of converting analog signal to digital signal. The accuracy depends on the sampling frequency and the number of bits used to describe the levels.
part of the interface that converts ordinary (analog) voltages, such as the detected NMR signal, into digital (number) form, that can be read by the computer.
A circuit that converts an analog signal into a digital signal. With a continuous input signal this device will check the signal several times per second (referred to as sampling), then assign values to the samples and represent them as a binary number (referred to as quantization and encoding).
Component of a scanner. Converts the analogical electric signals into exploitable numerical signals by a computer.
(A/D Converter) is a device that converts analog information (a photograph or video frame) into a series of numbers that a computer can store and manipulate.
