In this section, we are going to take a look at the types of ADC modules and the conversion process of the signal. We will get insights into answering these questions: How the ADC module takes care of the incoming data? Do all the ADC modules need external signal conditioning circuitry and amplification? How does the ADC module provide the data output? How is the quality of the ADC measured? What are the calculations required while processing the data?
ADC modules are a part of the signal conditioning circuitry in a microprocessor or a microcontroller. Unlike the RasPi, most microcontroller and microprocessor-based boards have ADC modules embedded, and the signal conditioning circuitry too. Most sensors can be directly integrated with these kinds of processors. Practically, in sophisticated systems, these conditioning networks have many stages for taking care of the incoming data. Some processors have dedicated signal processing cores or units to handle the data...
