I will study them thoroughly tomorrow, it is late night here. Without considering the specs I gave(say 0.05Hz move to 0.5Hz), since they may be over stict due to my ignorance, what do you suggest to implement the practical most narrow low pass filter on a cortex-M4? Shall I use averaging or halfband FIRs? | |
