Q2. Bit arbitration and its significance
Ans. 
Bit arbitration is the process of resolving conflicts when multiple devices try to access the same bus simultaneously.
• Bit arbitration is important in multi-master systems where multiple devices can initiate data transfer.

• It ensures that only one device gains control of the bus at a time.

• Different arbitration schemes include priority-based, round-robin, and collision detection.

• For example, in a CAN bus system, the devic...read more

Q4. Why can bus uses 120 ohm resistance
Ans. 
120 ohm resistance is used in CAN bus to match the characteristic impedance of the transmission line.
• CAN bus is a differential signaling system that requires a balanced impedance to prevent signal reflections.

• The 120 ohm resistance matches the characteristic impedance of the transmission line, which is typically 120 ohms.

• Without the proper impedance matching, signal reflections can cause data errors and reduce the maxi...read more
