Re: [Haskell-cafe] How to implement a digital filter, using Arrows?

your function corresponds with Control.Arrow.Transformer.Automaton. If you frame your function is such most of your plumbing is taken care of. http://hackage.haskell.org/packages/archive/arrows/0.4.1.2/doc/html/Control-... On 18/10/2011 1:46 PM, Captain Freako wrote:

Hi all,

If I have a pure function, which maps `(input, initialState)' to `(output, nextState)', what's the most succinct way of constructing a digital filter from this function, using Arrows?

Thanks, -db
