# Implicitly clocked synchronous signal

type Signal a = Signal' SystemClock a Source

Signal synchronised to the "system" clock, which has a period of 1000.

# Basic circuit functions

signal :: Applicative f => a -> f a Source

mux :: Applicative f => f Bool -> f a -> f a -> f a Source

# Boolean connectives

# Product/Signal isomorphism

Isomorphism between a `Signal`

of a product type (e.g. a tuple) and a
product type of `Signal'`

s.

Instances of `Bundle`

must satisfy the following laws:

`bundle'`

.`unbundle'`

=`id`

`unbundle'`

.`bundle'`

=`id`

By default, `bundle'`

and `unbundle'`

, are defined as the identity, that is,
writing:

```
data D = A | B
instance
````Bundle`

D

is the same as:

data D = A | B instance`Bundle`

D where type`Unbundled'`

clk D =`Signal'`

clk D`bundle'`

_ s = s`unbundle'`

_ s = s

fromList :: [a] -> Signal' clk a Source

Create a `Signal`

from a list

Every element in the list will correspond to a value of the signal for one clock cycle.
