Pull Request for DL-Simplified 💡

Issue Title: Denoising a simple sine wave.

• Info about the related issue (Aim of the project): The goal of this project is to denoise a simple sine wave using Convolutional Autoencoders, LSTM and advanced Convolution autoencoders. The noisy sine wave is cleaned up by reconstructing the signal through feature extraction and noise reduction.

Describe the add-ons or changes you've made 📃

In this PR, I have added a new feature that denoises a sine wave using a Convolutional Autoencoder. The steps include:

• Preprocessing the noisy sine wave
• Training a 1D Convolutional Autoencoder
• Visualizing the denoised signal along with the noisy and original signals

Type of change ☑️

What sort of change have you made:

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Code style update (formatting, local variables)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

How Has This Been Tested? ⚙️

• The code was tested using synthetic noisy sine wave data, and the model was trained on it.
• The output was visually compared by plotting the original, noisy, and denoised signals, showing effective noise reduction.

Checklist: ☑️

• My code follows the guidelines of this project.
• I have performed a self-review of my own code.
