摘要
提出了多点平均和展宽频带的算法。利用计算机的数据存储器作为数字式多点平均器的存储器 ,用于检测完全被噪声遮蔽的信号。当模拟 -数字转换 (ADC)器件采样频率一定时 ,采用展宽频带的方法可以实现对高频和很低频率信号的实时处理 ,从而提高了仪表的精度 。
It is put forward a new method of restoring signal covered with noise and widening frequency band of instrument.The core of the method is that our making full use of memory of personal computer takes for register of digital multi-point averager and that our increasing or decreasing collecting data point achieves high and low frequency signal collected when the time of ADC chip is fixed.This method makes the intelligent instrument can process some high and low frequencv signals covered with noise with higher precision.
