| 8. | The interpolate technology just like a " ruler " , the resolving power of the " ruler " affect that the sampling points are arrayed correctly on time axis , and is determined by the multiple of the double slope integral amplifier . so it is core in the whole project . the project apply the complicated program logical device ( cpld )
内插技术的应用使得随机采样理论能够得以实现，内插技术相当于测量用的“尺子” ， “尺子”最小分辨能力决定了最后采样点重新在时间轴上位置排列的真实可靠程度，这里尺子的最小分辨能力是由双斜率积分时间扩展器放大倍数决定的，所以说该模拟充放电放大电路在整个方案中是个很关键的部分。 |
| 9. | By using single - chip microcomputer c8051f060 and dds ad9852 , the instrument is easy to measure the transport characteristic of the high frequency tuner . by using c8051f060 to control dds chip ad9852 , a signal with high resolution , high transferring speed and pure spectrum is obtained . the output frequency range is up to 1000mhz . the system can give the frequency characteristic drawing of the high frequency tuner by connecting pc with usb
