## Overview
The Digital Filter Designer is a powerful application built using PyQt5 and Matplotlib. It allows users to design and visualize digital filters, including standard filters and all-pass filters, and generate corresponding C code. This tool is ideal for students, researchers, and engineers working in the field of digital signal processing.

## Main Features
- **Z-Plane Plotting**: Visualize zeros and poles on the Z-plane.
- **Standard Filter Design**: Design Butterworth, Chebyshev, Bessel, and Elliptic filters.
- **All-Pass Filter Design**: Create custom all-pass filters and predefined all-pass filters.
- **Real-Time Signal Plotting**: Load signals from CSV files or draw signals using the mouse.
- **Transfer Function Visualization**: View the magnitude and phase response of the designed filter.
- **C Code Generation**: Generate C code for the designed filter for easy integration into other projects.
## Getting Started
### Prerequisites
Ensure you have the following installed:
- Python 3.x
- PyQt5
- Matplotlib
- NumPy
- SciPy
- Pandas
- Jinja2
- PyQtGraph
### Installation
1. Clone the repository:
```sh
git clone https://github.com/HarmoniCode/Digital-filter.git
```
2. Navigate to the project directory:
```sh
cd Digital-filter
```
3. Install the required packages:
```sh
pip install -r requirements.txt
```
### Running the Application
1. Navigate to the project directory:
```sh
cd Digital-filter
```
2. Run the main application:
```sh
python main.py
```
## Usage
### Z-Plane Plotting
- Add zeros and poles to the Z-plane by entering their coordinates and clicking the "Add Zero" or "Add Pole" buttons.
- Visualize the effect of the zeros and poles on the filter's transfer function in real-time.
### Standard Filter Design
- Select a standard filter type (e.g., Butterworth, Chebyshev) from the dropdown menu.
- The application will automatically plot the zeros and poles for the selected filter.
### All-Pass Filter Design
- Create custom all-pass filters by adjusting the parameter [a](http://_vscodecontentref_/0) using the spinbox.
- Select predefined all-pass filters from the list of checkboxes.
### Real-Time Signal Plotting
- Load a signal from a CSV file by clicking the "Load Signal" button.
- Draw a signal using the mouse by selecting the "Draw using Mouse" option.
### Transfer Function Visualization
- View the magnitude and phase response of the designed filter in the transfer function plot.
### C Code Generation
- Generate C code for the designed filter by clicking the "C Code" button.
- The generated code will be displayed in a pop-up window and saved and .c file .
