This example shows how to capture a single channel analog inputs, analog (ADC) will be converted to analog data and the data transferred by DMA to memory.
To enhance control ability and accuracy, the filter algorithms are adopted by PLC when gathering analog data and implementing the PID algorithm in frequency conversion control.
A lot of analog data show that the ground potential varies most in the edge areas of the concrete when the resistance of the concrete is smaller than that of the soil.
大量模拟计算表明,当混凝土的电阻率比土壤的电阻率小很多时,地面电位是在混凝土的边角附近变化最大。
The experiment results acquired from synthetic analog data proves better performance of the presented filter in eliminating the Rician noise at low level SNR.
基于模拟数据的实验结果表明,在信噪比低的情况下复扩散滤波器具有更好的消除赖斯噪声的效果。
The development of faster, cheaper, and smaller input signal samplers (ADCs) and output converters from digital data to analog data (DACs) began to make real-time DSP practical.
The pressure and depth monitoring system in the control system consist pressure and depth sensor produced by Germany STAMO and ADVANTECH analog data acquisition card-PCI1710.
Both of FSQ and SSY-II instruments were set to record the digital and analog data simultaneously in Lanzhou Observatory in 2002. The apparent difference between two kinds of data was found.
In the next article, I「ll describe how to use the iMic to gather an analog data stream, and I」ll show you how to use one of the SPEs to turn the system into a useful spectrum analyzer.
In many modern microcomputer-controlled meters and instruments, it is often necessary to collect the analog data that are slowly variable for analysis.
