How can the accuracy of a frequency counter be improved?
- A By increasing the accuracy of the time base
- B By using slower digital logic
- C By using faster digital logic
- D By improving the accuracy of the frequency response
Correct answer: A — By increasing the accuracy of the time base. From the official ISED question bank, verified word for word.
Why
A frequency counter measures how many cycles occur within a specific time window, so its accuracy depends entirely on how precisely that window is defined. The full explanation — and one for every question — is in Pro.
