输入您的问题The 16-bit FIR filter module implements FIR Filter using DMAC instructions
that
effectively executes 2 filter taps in a cycle. This module can support up to
255 order FIR filter.
Now my question is: can we obtain the filter coefficient whatever we want,
without the help of ezfir_matlab module?
Because in my projedt I want the filter can varies due to different signals.
Fixed filters can not reach my goal

您好,我采集三相电网电压参数,采集三相电压信号,然后分别对采集的三相电依次进行三次FIR滤波,怎么会出错,也就是说结果不是正弦波了,但是我只执行一个FIR滤波没有问题,我也是用的FIR16库函数,汇编源码!
