analog-to-digital converter
Noun: A hardware device that transforms a continuous analog signal (such as voltage, sound, or light) into a discrete digital signal represented by binary numbers (a series of 0s and 1s). This process, called analog-to-digital conversion, is fundamental for digital systems to process real-world information.
The term "analog-to-digital converter" is used to describe the specific component responsible for the conversion process. It is often abbreviated as ADC. * The microphone's signal is fed into an analog-to-digital converter before the computer can process it. * The quality of the recording depends heavily on the resolution of the analog-to-digital converter. * Modern oscilloscopes have a built-in high-speed analog-to-digital converter.
- Specification Context: Often discussed in terms of its technical specifications, such as sampling rate (how often it reads the analog signal) and bit depth or resolution (the precision of each digital sample).
- An audio interface with a 24-bit analog-to-digital converter provides a very detailed digital representation of the sound.
- ADC: The standard and most common abbreviation.
- The microcontroller has a 10-bit ADC on chip.
- A/D Converter: An alternative written form.
- Digitizer: A broader term that can refer to a device or system performing analog-to-digital conversion, often for complex signals like video.
- Analog-to-Digital Conversion (ADC): The name of the process itself.
- Analog-to-digital conversion is the first step in digital signal processing.
- Digitizer (in many technical contexts)
- A/D Converter
- Digital-to-Analog Converter (DAC or D/A Converter): A device that performs the reverse function, converting digital signals back into analog signals.
- The DAC converts the digital music file back to an analog signal for the speakers.
