和模拟技术相比,数字技术有许多优点,更由于近年来,数字部件的价格大幅度下降,它在电子产品中的应用日趋强劲。那么,模拟技术是否越来越不重要,甚至在将来终于退出历史舞台呢?中国航天工业总公司771所研究员陈震初说:“随着数字技术的发展,模拟技术并不是变得不重要,也绝不会退出历史舞台,恰恰相反,数字技术的发展和广泛应用对模拟信号处理提出了更高的要求,推 Compared with analog technology, digital technology has many advantages, but also because in recent years, the price of digital components dropped significantly, it is increasingly strong in the application of electronic products. So, analog technology is less and less important, and even in the future finally exit the stage of history? Chen Xiachu, 771 researcher at China Aerospace Corporation said: "With the development of digital technology, analog technology is not become less important, and must Will not withdraw from the stage of history, on the contrary, the development of digital technology and extensive application of analog signal processing put forward higher requirements, push
