Line Coding Visualizer

A C++ project that simulates and visualizes digital line coding schemes commonly used in physical layer communication.
It supports encoding binary data using Unipolar NRZ, Polar NRZ-L, Bipolar AMI, and Manchester encoding techniques, and generates waveform data for visualization via Gnuplot.

Features

• Encode user input binary strings using:
  • Unipolar NRZ
  • Polar NRZ-L
  • Bipolar AMI
  • Manchester Encoding
• Generates data files (.dat) for waveform plotting
• Prints Gnuplot script to visualize encoded waveforms
• Demonstrates concepts of inheritance, polymorphism, and abstract classes in C++

Sample Output

Gnuplot-generated waveform for 10101 using Manchester encoding:

Technologies Used

• C++
• Gnuplot (for waveform plotting)
• Command-line interface

▶️ How to Run

1. Compile the code:

   g++ LineCodingVisualizer.cpp -o linecoder
   

2. Run the program: ./linecoder

3. Follow prompts to enter binary data and choose the encoding scheme.

4. Copy the printed Gnuplot script into a .gnu file (e.g., plot.gnu) or paste into terminal if Gnuplot is installed.

5. Generate waveform image: gnuplot plot.gnu

Output Files

signal.dat → voltage levels over time line_coding_waveform.png → final waveform image Gnuplot script for visualization
