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 is the main purpose of ADC?

  The main purpose of ADC is to convert the input analog signal into a digital signal.
  ADC, or analog-to-digital converter, is mainly used to convert continuously changing analog signals into discrete digital signals. The implementation process of ADC usually includes four steps: sampling, holding, quantization, and encoding.
  

• 2. 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 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.
