Abstract: A learning system with augmented reality is provided. The learning system includes a cloud server recording an operation history of a learner and providing feedback messages, and a mobile device having an image-capturing module capturing an image of a substantial object. Also, the learning system comprises an object database storing a simulated object corresponding to the substantial object, an identification module identifying the image and generating image information, and a processing module which receives and analyzes the image information, obtains the simulated object from the object database according to analyzing results, and displays the simulated object on a display interface of the mobile device. The learning system allows learner to operate simulated object operation instructions on the display interface or directly operate the substantial object to control a display status of the simulated object, and the operation history of learner is transmitted to the cloud server.

Abstract: A signal processing method and apparatus. According to the signal processing method, phase change processing can be performed on to-be-sent data signals according to a phase status of a data synchronization signal and phase statuses of the to-be-sent data signals, so that phase differences between a majority of to-be-sent data signals in the processed to-be-sent data signals and the data synchronization signal meet a certain condition, thereby reducing a volume of coupling crosstalk, generated by the to-be-sent data signals, on the data synchronization signal and further reducing impact of simultaneously switching noise (SSN) on a system.
