E4A05 : What is the purpose of using a prescaler with a frequency counter?
A
Amplify low-level signals for more accurate counting
B
Multiply a higher frequency signal so a low-frequency counter can display the operating frequency
C
Prevent oscillation in a low-frequency counter circuit
D
Reduce the signal frequency to within the counter's operating range
Correct Answer: Reduce the signal frequency to within the counter's operating range
