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 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.

• 2. How to convert analog to digital without ADC?

  Analog to digital conversion without ADC can be achieved through PWM circuit. This method is suitable for those main control chips without built-in ADC, which needs to be solved by two GPIOs and an operational amplifier. The basic principle is to use an integral circuit to convert the PWM wave into a smooth DC voltage, and then continuously adjust the PWM duty cycle by comparing it with the voltage to be measured until the output of the comparator changes from 0 to 1, and record the current PWM duty cycle, thereby realizing the measurement of the analog voltage.

• 3. What is the difference between the input and output of an ADC?

  The input of ADC (Analog-to-Digital Converter) is analog quantity and the output is digital quantity.
  The main function of ADC is to convert continuous analog signal into discrete digital signal. In electronic systems, analog signal usually refers to continuously changing voltage or current, such as the signal obtained from microphone or sensor. The amplitude and frequency of these analog signals can change continuously, while digital signals are composed of a series of discrete values, usually expressed in binary form.
  Input: The input of ADC receives analog signals, which can be in the form of continuously changing physical quantities such as voltage and current. The amplitude and frequency of analog signals can change continuously, such as the voltage range from 0V to 5V.
  Output: The output of ADC is digital signal, which is composed of a series of discrete values, usually expressed in binary form. The advantage of digital signals is that they can be calculated and processed quic
