# FIR Filter Designer

FIR Filter Designer App using Window Method written in Python.

## Installation

1. Download the .rar file from https://github.com/kirkalyn13/fir-filter-designer/releases/tag/v.1.0

2. Extract/Unzip the .rar file. It should produce a directory containing the "FilterDesigner.exe" file and other software files.

## Usage

Run the "FilterDesigner.exe" from the unzipped directory.

Input Parameters:

- Filter Types

   1. Lowpass filter

   2. Highpass filter

   3. Bandpass filter

   4. Bandstop filter

- Window Types

   1. Rectangular

   2. Bartlett

   3. Hanning

   4. Hamming

   5. Blackman

- Sampling frequency in Hz

- Number of FIR Filter taps.  # Must be odd and minimum of 3.

- Lower cutoff frequency in radians.  # Set to 0 for High Pass Filter.

- Higher cutoff frequency in radians.  # Set to 0 for Low Pass Filter.

Output:

- Designed FIR Filter Coefficients

- Frequency Response Plot
