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. What are DAC and ADC?

  ADC and DAC are two important concepts in digital electronics. ADC stands for "analog-to-digital converter", which can convert analog signals into digital signals. DAC stands for "digital-to-analog converter", which can convert digital signals into analog signals. Both converters play an important role in many electronic products, such as mobile phones, televisions, stereos, etc.

• 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 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
