What does a frequency counter do?
C
Answer
Transmitters and receivers
Type
A
It measures frequency deviation
B
It generates broad-band white noise for calibration
C
It makes frequency measurements
D
It produces a reference frequency
Answer Notes
A frequency counter is an essential piece of test equipment specifically designed to measure the frequency of an applied periodic signal. It works by counting the number of wave cycles or pulses that occur within a highly precise time interval known as the gate time.
Distractors in this question describe entirely different pieces of equipment. A frequency standard or signal generator produces a reference frequency, while a noise generator creates broad-band white noise for testing. Additionally, measuring frequency deviation requires a specialized modulation meter, not a standard frequency counter.
