 - **DC Component**: Unipolar encoding has a non-zero average amplitude due to the constant positive voltage. This creates a **direct current (DC) component** in the signal. - **DC Component**: Unipolar encoding has a non-zero average amplitude due to the constant positive voltage. This creates a **direct current (DC) component** in the signal.

 - **Incompatibility**: Unipolar signals cannot pass through media that do not support the DC component (e.g., capacitors or transformers). - **Incompatibility**: Unipolar signals cannot pass through media that do not support the DC component (e.g., capacitors or transformers).
  
 In summary, unipolar encoding is a basic method for representing digital data using voltage levels, but its limitations make it less commonly used in modern communication systems. Other encoding schemes, such as bipolar encoding or Manchester encoding, address some of these drawbacks. 🌐🔌 In summary, unipolar encoding is a basic method for representing digital data using voltage levels, but its limitations make it less commonly used in modern communication systems.
