Signal Processing Library

This library provides functions for calculating biquad coefficients of Butterworth filters, including lowpass and highpass filters. It uses analog-to-digital transformation techniques like the bilinear transform and frequency warping.

Features

• Butterworth Filter Design: Calculates biquad coefficients for Butterworth filters.
• Lowpass & Highpass Filters: Supports both filter types.
• Complex Number Support: Uses num_complex for complex operations.
• Analog to Digital Transformation: Converts analog filter specs to digital coefficients.

Installation

Add the following to your Cargo.toml:

[dependencies]
ndarray = "0.16"
num-complex = "0.4"
