According to a Design News article, digital signal controllers (DSCs) are offering a boost to embedded sensor-based applications in search of greater intelligence. The time-tested method of using sensors and computing intelligence to monitor and control a process typically employs analog signal conditioning, sampling and digital conversion, and a microcontroller. DSCs essentially roll all of these functions into a single chip. The result is a more cost-effective solution. But DSC makers also claim they can better filter sensor signal noise, compensate for sensor degradation over time, and deal with sensor-to-sensor variability.
