chirper-py 1.0

Package for signal analysis

Chirper

Introduction

Chirper is a Python package used for Digital Signal Processing. It implements different tools to create, import and export signals, as well as integral transforms and different modulation methods, useful when using signals to carry information.

How to install

In order to install SignPy, simply import it from PyPi by running

py -m pip install chirper-py

Contained subpackages

Currently, the implemented subpackages are:

• modulation - Contains methods used for signal modulation. Right now, it allows for AM, FM and PM.
• sgn - Contains the code that allows the user to create signals in different ways, as well as importing and exporting them from files. As of now, both one dimensional signals (such as audio signals) and two dimensional signals (such as images) are implemented, and there are plans to implement three dimensional signals (such as videos).
• transforms - Contains different integral transforms which can be applied to signals. The ones currently implemented and the signals they can be applied to are:
  • fourier: Fourier transform (1D, 2D).
  • ifourier: Inverse Fourier transform (1D, 2D).
  • hilbert: Hilbert transform (1D).
  • cosine: Cosine transform (1D, 2D).
  • sine: Sine transform (1D, 2D).
  • stft: Short-time Fourier transform (1D).

Changing default methods

Within the chirper folder, there is a file config.py. It contains the default configurations used for the code, such as the default method used to calculate a Fourier transform, or the default method for convoluting two signals.

I want to eventually redesign this system, as it probably is very limiting. However, right now it gets the job done, so it isn't in the top of my priorities.
