Talk:Apply a digital filter (direct form II transposed)

Task description

Although this task has a number of implementations, the task description is inadequate.

It's not just that it refers to an external site (looks like a college text) but it leaves implicit too many details.

We're representing the transfer function for a low pass filter here. But nothing was said about the units involved (seconds or frequency). So there's no real way of judging the accuracy of the answers. They could all be wrong and no one would know. Or, put different, updating the task to flesh out the missing details in the task description is probably harder for many of us than translating an implementation to another programming language. --Rdm (talk) 20:31, 18 May 2023 (UTC)

Don't ask me: I'm at a complete and utter loss trying to reason why, in the Phix entry, starting the second j loop at 1 or 2 makes absolutely no difference whatsoever... --Petelomax (talk) 13:35, 20 May 2023 (UTC)
