Analog to digital Converters (ADCs) are electronic devices used to convert continuously varying Analog signals into discrete Digital signals. This process usually includes three steps: sampling, quantization and coding. Sampling means capturing the instantaneous value of an analog signal at a fixed frequency; Quantization approximates these transient values to the nearest discrete level; Finally, the encoding converts the quantized value into binary numeric form.
Application
ADCs(Analog-to-digital Converters) is widely used in a variety of scenarios, such as audio and video recording, measuring instruments, wireless communications, medical devices, and automotive electronics. For example, in audio devices, the ADC is responsible for converting the sound signal captured by the microphone into a digital format for easy storage and transmission.
FAQ about Data Acquisition - Analog to Digital Converters (ADC)
-
1. What is analog data acquisition?
Analog data acquisition refers to the process of converting continuously changing signals of physical quantities into digital signals so that computers can process and record these signals. This process involves the use of an analog quantity collector, which is a hardware device that can convert analog signals of physical quantities into digital signals and then transmit them to a computer for processing and recording.

How many types of ADC are there?
The types of ADC (Analog-to-Digital Converter) mainly include:
1. Integral ADC: Its working principle is to convert the input voltage into time (pulse width signal) or frequency (pulse frequency), and then obtain the digital value by the timer/counter. The advantage of the integral ADC is that it can obtain high resolution with a simple circuit and has strong anti-interference ability, but the disadvantage is that the conversion rate is extremely low because the conversion accuracy depends on the integration time.
2. Successive approximation type (SAR ADC): The successive approximation ADC is one of the most common architectures. Its basic principle is to convert by gradually approximating the value of the analog input signal. The advantages of the successive approximation ADC are high speed and low power consumption. It is cheap at low resolution, but expensive at high precision.
3. Parallel comparison type/serial-parallel comparison type ADC: The parallel comparison type AD uses m

3. What is the principle of analog-to-digital converters?
The working principle of the analog-to-digital converter (ADC) is to convert analog signals into digital signals through four processes: sampling, holding, quantization, and encoding.
The main components of the analog-to-digital converter include samplers and quantizers, which work together to convert continuous analog signals into discrete digital signals. This process requires a reference analog quantity as a standard, and the maximum convertible signal size is usually used as the reference standard. The basic principles of the analog-to-digital converter can be summarized as follows:
Sampling: The analog-to-digital converter first samples the input analog signal through a sampling circuit, that is, discretizes the analog signal on the time axis.
Holding: The sampled signal is held by the holding circuit for the next quantization and encoding process.
Quantization: The quantization process is to divide the amplitude of the sampled and held analog signal into a finite number of le
