Question

1. which section of a function generator sets start and stop frequencies?

a frequency section
b modulation section
c duty cycle
d sweep section

Explanation:

The sweep section of a function - generator is used to set the start and stop frequencies for a frequency - sweep operation. The frequency section usually sets a single fixed frequency, the modulation section deals with amplitude, frequency or phase modulation, and the duty - cycle section is related to the proportion of time a signal is high in a periodic waveform.

Answer:

D. Sweep section
