A device that converts analog information (a photograph or video frame) into a series of numbers that a computer can store and manipulate. All digicams use an A/D converter, the higher the bit rate the better the output. Modern hi-res digicams employ a 12-bit or 14-bit A/D to increase the dynamic range (range of light from highlight to shadow).
An electronic device that converts a continuous analog signal to digital form expressed usually as a set of binary digits. The digital form is usually a set of 8 or more binary bits which quantizes an analog signal to 2^n bit levels.
A device that digitizes an analog waveform.
A processor that converts analog electrical signals into digital data. The converter samples the electrical signal every few milliseconds. The signal is then quantized into a digital word. The larger the digital word, the more accurate the sample.
Analog-to-Digital converter. A circuit board or integrated circuit that converts analog input signals to digital equivalent-weight output signals.

A circuit that converts an analog audio signal into a digital audio signal.
The conversion of analog signals into digital signals. The analog signal is sampled every few milliseconds and its level is quantized into a digital word. The larger the digital word, the more accurate the representation of the analog value. See Quantization 1 and Sampling frequency The 02R uses 20-bit linear analog-to-digital converters for most of its analog inputs.
A circuit which converts analogue waveforms into a series of binary values. The more bits a converter has, the greater the resolution of the sampling process.
Analog/Digital converter. Converts analog voltages or current values to digital information that can be processed by a computer.
The A/D Converter changes the analog signal from the CCD camera into a digital signal which is read by the computer. How finely the signal is divided digitally is determined by the bit depth of the A/D Converter.
A device which converts analogue signals into digital signals.
Abbreviation for analog-to-digital converter, an electronic device for quantifying a (typically) continuous-time voltage signal to a numeric discrete-sample sequence. A/D converters are commonly used in imaging systems to convert pixel values to numeric equivalents, in radar systems to convert signal intensity to digital values for subsequent signal processing, and in many other areas of in situ and remote sensing. Important A/D converter characteristics include the number of unique quantization levels (expressed by the number of binary bits in the resulting numeric values) and the speed of quantization.
A device used to convert analog data to digital data. Analog data is continuously variable, while digital data contains discrete steps.
An electronic device, often an integrated circuit, that converts an analog voltage to a digital value. All digital instruments use an A/D converter to convert the input signal into digital information.
See analog-to-digital converter.
Converts an analogue signal into a digital signal.
Analogue to Digital Converter. A circuit that translates an analogue signal into digital
A device that takes analog inputs and converts them to digital signals. For example, a sine wave input can be converted into a series of numbers that represent the value of the input curve at any given point on the curve. The resolution of the converter is determined by the number of bits (the more the better) and the sample rate (the faster the better).
Analog to Digital Converter. Generic term for any device that changes continuous wave (analog) activity to binary (digital) codes, or vice versa.

(Also A/D or ADC) Short for analog-to-digital converter. Converts real-world analog signals into a digital format that can be processed by a computer.
Analogue to Digital (A/D) Converters are used with LCD monitors with an analogue interface. The analogue signal is converted into a digital signal for display on an LCD panel. LCD monitors with only a digital interface require a dedicated graphics adapter and connectors, which come in varied formats.
Analog to Digital Converter. An electronic device that converts varying sinusoidal signals from instruments into binary code for a computer.
A device (usually an IC chip on your data acquisition board) which accepts an analog signal and outputs a corresponding digital value.
a device that converts continuously varying analog signals from instruments that monitor such conditions as movement, temperature, and sound into binary code (that is, 1s and 0s) for the computer.
The A/D converter works with the CCD. It's the device that actually converts the information from the CCD into digital format.
A device that accepts an analog signal at its input, and outputs a digital version of the signal.
Analogue to digital converter. A device that converts data from analogue to digital form, e.g. an audio CD is made by converting analogue sound signals into digital data.
Analog-to-digital converter. In a CCD camera system, the electronic circuitry that converts the analog information (continuous amplitudes) acquired by the detector into the digital data (quantified, discrete steps) used for image display.
A hardware device that reads an analog signalâ€”typically a voltageâ€”compares it to a reference signal, and converts the resulting percentage to a digital value. Short for analog-to-digital converter. Abbreviated ADC. The reference signal represents 100%. An n-bit A/D converter has a maximum value of 2**n - 1 and a resolution of Vref/2**n. See also D/A converter. [ more
