Signal Conditioning
Sensors that are used to collect the data from the environment often don’t produce signal of characteristics optimal for an analog to digital converter (ADC) to translate to digital data. Additionally, these signals can be subject to electromagnetic interference (EMI) that introduces noise, having a negative impact on the reliability of the data. To make this analog input readable for the processing unit and dependable enough to give the desired quality of data the signal has to undergo a process of signal conditioning.
