In fact, the measurement and control circuit is a further extension and expansion of analog electronic technology and digital electronic technology, mainly discussing some typical and common circuits . Therefore, it is the foundation to learn analog and digital electronics, and the operational amplifier is a core component of the measurement and control circuit.

Measurement and control circuit, that is, measurement control circuit, an important part of the measurement and control system. The measurement and control system is mainly composed of three parts: sensor, measurement and control circuit and actuator. In the measurement and control system, the measurement and control circuit is the most flexible part. It has the characteristics of easy amplification, easy conversion, easy transmission, and easy adaptation to various use requirements. The performance of the measurement and control system, as well as the entire machine and generation system, depends to a large extent on the measurement and control circuit.
