外文翻译--DSP的发展、现况及其应用.docVIP

DSP Development, the Status and Its Application Digital signal processing (DSP) is involves many disciplines and widely applies in the many domain emerging disciplines. DSP has two kinds of meanings: digital Signal Processing, Digital Signal Processor. We often say that what DSP refers to the digital signal processor. The Digital Signal Processors are suitable for to complete digital signal processing operation of the processor. Since the 1960s, with the computer and the information technologys’swift development,, the digital signal processing technologies has arisen at thehistoric moment and obtains the rapid development. In the past more thean 20 years,the digital signal processing has widely applied in the field of communiation and others. The digital signal processing uses the computer or the special-purpose handling equipment,carries om processing and so on fathering, transformation, filter, estimating, value, enhancement,compression,recognition by the digital form ,to lbtian the signal form which the piople need. The digital signal processing tskes the nemerous disciplines as the retionale, whose scope is extremely applied. For example, in mathematics domain,the calculus,the probability statistics,the stochastic process,the numerical analysis and so on.They are the digital signal processing basic tool and theyare relate to,the signal and the system,the cybernetics, the correspondence theory,the failure diagnosis and so on. Recently the emerging some disciplines,like the artificial intelligence, the pattern recognition, the neural networks and so on,are inseparable with the digital signal processing. It can be said that digital signal processing takes many classics system infos owm rationale,simultaneously causes itself to becone a seric\es if energing disciplines the rationale. The DSP is mainly applied in the digital signal processing,the siming to can satisfy the real-time signal processing,therefore it needs tbe digital signal processing operation executin
