Features: This book is a national planning textbook for the "10th Five-Year Plan" and primarily serves as a textbook for undergraduate students majoring in "Measurement and Control Technology and Instruments." It is also suitable for engineers, researchers in related fields, and graduate students in adjacent disciplines. Compared to the first edition, it places greater emphasis on the explanation of common content and broadens its applicability. The book introduces the functional blocks and overall connections of measurement and control circuits commonly used in industrial production and scientific research, enabling readers to understand how to apply electronic technology to solve tasks in measurement and control, thereby bridging the gap between electronic technology and measurement/control for rational circuit design and functional block selection. The content includes: the functions and main requirements of measurement and control circuits, their types, composition, and development trends; low-drift, high-performance measurement amplifiers, isolation, and controllable amplification circuits; various modulation, frequency modulation, phase modulation, pulse-width modulation, and demodulation circuits used in precision measurement to separate signals from noise and improve the signal-to-noise ratio, as well as various RC active filter circuits, integrated filters, and tracking filters; algebraic, calculus (including PID), and eigenvalue operation circuits used to complete complex measurement and control tasks, as well as sampling and holding circuits, voltage and current conversion circuits, frequency conversion circuits, and analog-to-digital conversion circuits; fine-grained and directional discrimination circuits commonly used in incremental digital measurement; electrical testing circuits for frequency, phase, and pulse parameters; pulse-width control and frequency conversion control circuits for continuous signals in digital and analog systems, binary and programmable logic control circuits, and digital control circuits; and through the analysis of several typical measurement and control systems, readers gain a deeper understanding of the overall structure of measurement and control systems and the role of measurement and control circuits within them. The entire book analyzes circuits based on key requirements such as accuracy, flexibility, rapid response, and reliability.
