Based on existing teaching conditions and actual needs, a virtual teaching experiment platform for a signal generator has been developed using LabVIEW. The platform realises a simpler function signal generator and a chaotic signal generator that are easy to operate by using virtual technology, which provides students with some simulation experiments without a physical laboratory. Compared with ...

Several studies in the auditory-perception literature hint that listeners may be able to anticipate the time of arrival of an approaching sound source. Two experiments are reported in which listeners judged the time of arrival of an approaching car on the basis of various portions of its auditory signal. Subjects pressed a computer key to indicate when the car would have just passed them, assum...

With the increase in the complexity of systems with mixed-signal components, many systems designers recognize advantages and necessity of the mixed-signal simulation of these systems as a whole. Unfortunately, modeling and simulating such complex systems takes an enormous amount of time. The first problem identified is the speed of analog simulation. The second problem is how is difficult to wr...

Abstract Focusing on the vertical array source signal recovery method, aiming at estimation deviation caused by environment mismatch in engineering application of virtual time reversal mirror technology, this paper proposes normalized technology through theoretical derivation and analyzes performance under change signal-to-noise ratio simulation. Finally, practicability method effectiveness mod...

The high-frequency signal injection-type maximum torque per ampere (MTPA) algorithm is usually employed to control the operation of interior permanent magnet synchronous motors (IPMSMs). MTPA exhibits good dynamic performance and anti-interference ability. However, due injection a current signal, problems such as ripple additional loss are encountered. Therefore, in this paper, virtual (VSIC) m...
