Question

1. which combination of buttons and controls set the amount of dc voltage that the ac signal rides on?

a burst width
b % modulation
c dc offset
d cmos level

Explanation:

DC offset is the control that sets the amount of DC voltage on which an AC signal rides. Burst width controls the duration of a burst - like signal, % modulation is related to the degree of modulation in a modulated signal, and CMOS level is related to the logic levels in a CMOS circuit.

Answer:

C. DC Offset
