# Filters Design

Deep dive into designing custom IIR and FIR filters with TorchFX.

## Overview

This tutorial covers:
- Understanding filter types (IIR vs FIR)
- Filter parameters and their effects
- Creating custom filter designs
- Filter stability and performance

## Prerequisites

- [Getting Started](../getting-started/getting_started.md)
- Basic DSP knowledge
- Understanding of frequency domain concepts

## What You'll Learn

- IIR filter design (Butterworth, Chebyshev, Elliptic)
- FIR filter design and windowing methods
- Filter cascading and parallel processing
- Analyzing filter frequency responses

## Filter Types in TorchFX

### IIR Filters
- Butterworth
- Chebyshev Type I & II
- Elliptic
- Linkwitz-Riley
- Shelving (High/Low)
- Parametric EQ
- Notch, AllPass, Peaking

### FIR Filters
- Standard FIR
- Designable FIR with custom coefficients

## Example Code

```python
from torchfx.filter import LoButterworth, ParametricEQ
import torch

# Example code will be added here
```
