  5. i belive its a fir it works really good, I downloaded it to a DSP Board. used a blackman window, its a band stop filter so when it reaches 60 hz it stops that frequency,  pluged in a couple numbers and tested...so  a fir filter will give better results? then a butterworth, or  bessel?  or is there something that makes them different?
