In digital instrumentation system, especially in digital electronics, digital computers have taken a major role in near every aspect of life in our modern world. Digital electronics is at the heart of computers, but there are many direct applications of digital electronics. All these digital electronics need data to be presented to them in a digital format (i.e. the data have to be digitally conditioned). This is called digital conditioning. Since computers are electronics devices, all the information they work with has to be digitally formatted. Therefore, if they are used to control a variable such as temperature, then the temperature has to be represented digitally. That's why we need digital signal conditioning to condition process-control signal to be an approximated digital format.^[1]
