Nice job in translating the digital filter example. I did wonder about the function name. Confusingly, the function probably should be called direct form II transposed rather than butterworth because its the vectors a and b that determine what type of filter is actually is. However, I've only really dabbled in DSP stuff - if some expert can inform us, that would help. (For a long time, I thought this function was the IIR filter but it can do FIR as well.) --[[User:TimSC|TimSC]] ([[User talk:TimSC|talk]]) 13:53, 17 December 2016 (UTC) |

Thanks for the kind words! I don't know diddly about the math or history of filters so I just picked a convenient name that seemed descriptive. I've changed the name as per your suggestion. -- [[User:Craigd|CraigD]] ([[User talk:Craigd|talk]]) 05:52, 22 December 2016 (UTC) |
