Control.Wire.Prefab.Sample

Signal sampling wires.

Simple samplers

class Arrow >~ => WDiscrete t (>~) | >~ -> t where

Sample the right signal at discrete intervals given by the left input signal.

• Depends: Current instant (left), last sampling instant (right).

Methods

discrete :: Wire e >~ (t, b) b

Instances

(AdditiveGroup t, MonadClock t m, Ord t) => WDiscrete t (Kleisli m)

keep :: WirePure >~ => Wire e >~ b b

Keep the signal in the first instant forever.

• Depends: First instant.
