环境监测无线传感器网络节点的设计 针对环境监测的要求,开发了一种兼容型的无线传感器网络节点系统。该系统以MSP430FG4618为核心,采用 CC2420 214G射频芯片,软件上移植了德州仪器( TI) ZigBee协议栈,并在应用层开发了通信程序。该系统可以组建成稳定的网状网络,功耗低,数据传输稳定.-Environmental monitoring wireless sensor network node designed for environmental monitoring requirements, to develop a compatible system for wireless sensor network node. The system MSP430FG4618 as the core, using radio frequency chip CC2420 214G, software transplanted Texas Instruments (TI) ZigBee protocol stack, and the application layer has developed a communication program. The system can be formed into a stable mesh networking, low power consumption, data transmission and stability.

1)生成2KHz和8KHz的混合信号，使该信号通过上述滤波器，观察滤波前后的波形变化和频谱分布情况。 2) 在改信号中加入高斯白噪声，观察滤波前后的波形变化和频谱分布情况3) 将上述滤波器改为中心频率为100KHz的带通滤波器，信号源为带外的90KHz和带内的100KHz的混合正弦信号，。 4) 用M文件实现上述低通滤波器。 -1) 2KHz and 8KHz to generate the mixed-signal, so that the signal through the above-mentioned filter, filter before and after observation of the waveform and spectrum distribution of the changes. 2) add to the signal in white Gaussian noise was observed before and after filtering and spectral waveform changes in the distribution of 3) will be replaced by the above-mentioned filter center frequency of 100KHz band pass filter, the signal source for the band and the band of 90KHz 100KHz Sine of the mixed signals. 4) achieve the above-mentioned documents with M low-pass filter.
