hellow,

what recomendations do you have for making FIR filter coefficients? I am using STM32 DSP software from apps note #14988.

http://www-users.cs.york.ac.uk/~fisher/mkfilter/

has calculators for different types of filters (scroll to the bottom).

Here another good site:

It lets you play around with the bandwidth and several types of basic filters and then calculates the coeff for you.

You can also download the java applet code which I did to adapt the sampling interval that is default 8000 in the examples.

Enjoy !
