Two key components of an automated process control system are the set point and the comparator. The set point device establishes a value for the desired state. The comparator device calculates how far the process is from this value.
By the end of this course, you will be able to
List examples of set point devices
Define an op-amp device
List the functions that a comparator performs on feedback and input signals
Explain how an error signal is produced in a differential amplifier
Define gain
