Question

1. what is the display used for on a function generator?

a to determine the amount of modulation applied to the output signal.
b to indicate the amplitude, frequency, function, and other parameters of the output signal.
c to display the shape of the output signal.
d to display the shape of an input signal.

Explanation:

A function - generator's display shows parameters like amplitude, frequency, and the type of function of the output signal. It is not mainly for determining modulation (a), showing output - signal shape (oscilloscopes are better for that, c), or input - signal shape (d).

Answer:

B. To indicate the amplitude, frequency, function, and other parameters of the output signal.
