摘要
为对试验中采集的信息进行滤波,获得所需要频率的数据,需要制作数字滤波器将采集的试验数据中其它频率信息滤除。利用MATLAB设计制作了带通数字滤波器,该数字滤波器可从采集的时域数据中提取出任何频率的数据,用该方法对实测数据进行滤波,方便实用,获得的数据准确。
In order to get data of the concerned frequency by filtering the information collected in test, it is needed to produce a digital filter to filter the information of other frequency. The article will focus on producing band-pass digital filtering procedures by the use of MATLAB. This digital filter can extract data of any frequency from the collected time-domain data. It is convenient and practical to obtain accurate data by this method.
