The purpose of transmitting an AC signal to a μC for ADC is to convert the analog signal into a digital signal that can be processed and analyzed by the microcontroller. This allows for more precise measurements and data collection.
DC offset is the difference between the average voltage of an AC signal and the reference voltage of the ADC. It is important to address because it can cause inaccuracies in the digital signal and affect the quality of the data being collected.
Some options for addressing DC offset include using a coupling capacitor, a high-pass filter, or a differential amplifier. These methods can help remove or minimize the DC offset from the AC signal.
The choice of DC offset option can greatly affect the accuracy of the ADC readings. If DC offset is not addressed properly, it can lead to errors in the digital signal and result in inaccurate readings. Therefore, it is important to carefully consider and test different options to find the most accurate solution.
Yes, there can be potential risks or limitations when transmitting an AC signal to a μC for ADC. These may include noise interference, voltage limitations, or limitations of the chosen DC offset option. It is important to carefully consider these factors and properly test and calibrate the system to ensure accurate and reliable results.
