# signal_composer

Library for composing signals from arrays and functions.

## Usage

### Creating Signals

#### From interpolated arrays

```python

signal = Signal([1, 0, 1, -1, 1])

```

#### From functions

```python

f = lambda x: x ** 3 - x ** 2

signal = Signal(f)

```

![](assets/signal_function.png)

```python

f = lambda x: x ** 3 - x ** 2

signal = Signal(f, function_input_span=[0, 1 + 0.25])

```

### Composing Signals

#### From adding signals

```python

signal_1 = Signal([0, 1])

signal_2 = Signal(lambda x: 1 + x ** 3)

composed_signal = signal_1 + signal_2

```

#### From lists

```python

signals = [

    lambda x: x ** 2,

    [-1, 0, 1],

    lambda x: 4 + x ** (1/2)

]

composed_signal = Signal.compose_from_list(signals)

```
