【Abstract】 This paper presents the construction of hardware and flow chart of software of an obstacle recurrence and amplification device (ORAD) based on the digital closed-loop modification technology. The digital closed-loop modification technology is creatively applied to the process of the obstacle recurring and amplifying. In addition, the obstacle source data is accurately modified by the sampling feedback data according to the ada’ptive fuzzy intelligent control algorithm. The proposed two methods enable the ORAD to overcome the waveform’s nonlinear distortion which is the drawback of the present devices of the same kind, such as the power amplifier, the relay test system, etc. Therefore the practicability of the ORAD is greatly enhanced.更多还原
