【摘要】 以切比雪夫等波纹逼近滤波器为理论基础,对MSP430F133单片机现场采集的可燃气体浓度信号进行滤波仿真,来阐述切比雪夫等波纹逼近低通滤波器的设计方法以及滤波器参数的优化,进而说明切比雪夫等波纹逼近滤波器的优越性能。更多还原

【Abstract】 This paper depends on the theory of Chebyshew equivalent ripple approximation DF,by taking the flammable gas signal collected by MSP430F133 MCU as an example to illustrate the design method of Chebyshew equivalent ripple approximation FIR low-pass DF and optimization of filter parameter,then explains the good performance of Chebyshew equivalent ripple approximation DF.更多还原
