Question 1
What is the formula for calculating phase velocity?
- vₚ = 1/√(RC)
- vₚ = 1/√(LC)
- vₚ = 1/√(GC)
💡 Hint: Look for the relationship involving L and C.
Question 2
Group velocity is different from phase velocity because:
- True
- False
💡 Hint: Recall the definitions of both concepts.

Question 1
Design a communication system needing precise timing. Given a phase velocity of 0.7c and a communication line of 1000 meters, calculate the propagation delay.
💡 Hint: Don’t forget to convert c into meters per second when calculating.
Question 2
If an RF circuit experiences a mismatch leading to a significantly decreased group velocity, what impact does this have on pulse transmission?
💡 Hint: Think about the effects of speed changes on signals.
