Part of the problem is that the chip is just too intelligent - rather than a standard digital pulse it produces an analogue output that flummoxes the standard software used to test chips.
其中一个问题是芯片太“过于智能”了——与普通芯片的数字脉冲输出不同，它的输出是模拟信号，因此用于数字芯片的测试程序被它干扰了。
This dissertation performed the following work based on the research before: (1) We studied the modulation identification problem of analogue modulated signals.
本文在前人的研究基础上主要做了如下工作：(1)研究了模拟调制信号的识别方法。
