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.

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.

• 1. How does ADC convert analog to digital?

  The technology that converts analog sound signals into digital signals is called analog-to-digital conversion technology (Analog to Digital Converter, referred to as ADC). The function of ADC is to convert continuously changing analog signals into discrete digital signals. The process of analog-to-digital conversion can be completed by steps such as sampling, holding, quantization, and encoding.
  
  

• 2. What process converts analog to digital?

  There are three basic processes for analog to digital conversion:
  The first process is "sampling", which is to extract the sample value of the analog signal at equal intervals to turn the continuous signal into a discrete signal.
  The second process is called "quantization", which is to convert the extracted sample value into the closest digital value to represent the size of the extracted sample value.
  The third process is "encoding", which is to represent the quantized value with a set of binary digits. After these three processes, the digitization of the analog signal can be completed. This method is called "pulse encoding".
  After the digital signal is transmitted to the receiving end, a restoration process is required, that is, the received digital signal is converted back to an analog signal so that it can be understood by the receiver. This process is called "digital-to-analog conversion", which reproduces it as sound or image.

• 3. What is the difference between ADC and DAC?

  The main difference between ADC and DAC is that they process different types of signals and conversion directions.
  The main function of an ADC (analog-to-digital converter) is to convert analog signals into digital signals. This process involves sampling, quantization, and encoding, where sampling is the periodic measurement of the value of an analog signal at a certain sampling rate, quantization is the conversion of the sampled continuous values ​​into a finite number of discrete levels, and encoding is the conversion of the quantized discrete levels into binary code. The output of the ADC is a digital signal that can be processed and stored by a computer or other digital circuit for various applications such as digital signal processing, data logging, and communications. Common applications in life include microphones, digital thermometers, digital cameras, etc., which convert the actual perceived analog information into digital signals for further processing and analysis12.
