This course systematically describes the research object and theoretical basis of signal analysis and measurement technology, as well as the principle of typical sensors and measurement system. The basic knowledge of signal processing, such as sampling theorem, Fourier transform, discrete time signal analysis, etc., is introduced. Basic characteristics of measurement system are focused. The principle of commonly used sensors based on resistance transformation, capacitance transformation, electromagnetic transformation, piezoelectric are introduced. On this basis, the principles of measurement systems such as vibration, torque, pressure and flow are separately described.
