Calibration using Analog Signal Processing
In this chapter we will focus on calibration techniques based on analog signal processing. Almost all sensors require some kind of analog signal conditioning or amplification before the sensor signal can be converted and processed digitally. Basically, sensors produce an analog output signal only. But even for modern smart sensors with digital output, a standardized analog output signal is often desired as well. Therefore, we will first consider the possibilities of adjusting the transfer of an analog circuit for the purpose of calibration.
