This application simulates electrical signal propagation along transmission lines, demonstrating key phenomena including:

• Signal attenuation
• Propagation delay
• Impedance mismatches
• Reflection and transmission coefficients
• Standing wave patterns

Developed with Claude 4.0 Sonnet for educational and engineering analysis purposes.

Usage

Execute the signal_transmission_plot.py script, as it features the animation tab in addition to the analysis tab.

ANALYSIS TAB:

1. Adjust impedance values to see reflection effects
2. Modify line parameters to observe propagation changes
3. Change pulse parameters to study different signals
4. Use preset buttons for common scenarios

ANIMATION TAB:

1. Set parameters and click "Start Animation"
2. Watch signal propagate along transmission line
3. Observe incident (blue) and reflected (red) waves
4. Total wave (green) shows superposition
5. Use Stop/Reset to control animation

PRESETS:

• Matched: No reflections (Γ = 0)
• Open Circuit: Full positive reflection (Γ = 1)
• Short Circuit: Full negative reflection (Γ = -1)

Key Concepts:

• Γ = (ZL - Z0) / (ZL + Z0) - Reflection coefficient
• Signal speed = c / √εr where c is speed of light
• Attenuation reduces amplitude with distance
