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

[A].	2 kV, 0.5 kV
[B].	1 kV, 0.5 kV
[C].	0.75 kV, 0.25 kV
[D].	0.5 kV, 1.5 kV

Answer: Option C

Explanation:

3-10-45-1

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.
