For the same frequency interference with ultrasonic which is difficult to eliminate with filter in the flow measurement of the engine thermal equilibrium, this paper puts forward the way which with pseudo-random code modulation sine wave as the drive signal for ultrasonic transducer. This paper analyzes the interference in the flow measurement of engine… (More)
The power spectral estimation is an important element in the random signal analysis. The paper will introduce the principles of the classical power spectral estimation and modern power spectral estimation, analyses their characteristics and application in MATLAB simulation. The variance obtained by the classical power spectral estimation is inversely… (More)
