What are the values of Emax and Emin displayed on the oscilloscope, when a 1 kV P-P carries is modulated to 50%?

• 2 kV, 0.5 kV
• 1 kV, 0.5 kV
• 0.75 kV, 0.25 kV
• 0.5 kV, 1.5 kV

Correct Answer: 0.75 kV, 0.25 kV

Explanation:

E_max - E_min = 0.5 x 1 kV = 0.5 kV

2E_max = 1.5 kVi, E_max = 0.75 kV

E_min = 0.25 kV.
