在核信号检测与控制系统中，从传感器输出的信号，一般都很微弱，为了避免信号在远距离传输过程中衰减、严重失真，这就需要对信号进行调制解调。在Win7系统下，使用LabVIEW2010设计了一个信号调制与解调系统。并且在该系统中分别采用Buaerworth滤波器、Chebyeshev（Ⅰ型）滤波器、椭圆滤波器对信号进行滤波了处理，比较结果发现．使用Butterworth滤波器得到的解调信号较后两种滤波器的好。

In the nuclear signal detection and control system, the output signal from the sensor is generally weak, in order to avoid signal attenuation in long-distance transmission and a serious distortion, which requires the signal modulation and demodulation. With the use of LabVIEW2010 a signal modulation and demodulation system is designed in Win7 system. And in this system Butterworth filter, Chebyeshev （I type） filter, elliptic filter are used for filtering the signal processing. The result shows that the Butterworth filter to demodulate the signal received a good results compare to another two kinds of filters.
