| 9. | 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。 |
