A sound is sampled at 16,000 samples per second. According to the Nyquist theorem, what is the highest frequency that can be represented?.
- A.4,000 Hz
- B.8,000 Hz
- C.16,000 Hz
- D.32,000 Hz
Model answer
What a good answer should say
- 8,000 Hz
Explanation
Why this works
The Nyquist theorem states that the sampling rate must be at least twice the highest frequency being represented. Therefore, the highest representable frequency is 16,000 ÷ 2 = 8,000 Hz.
