48.4 kHz
22,050 Hz
44.1 kHz
48 kHz
Answer is Right!
Answer is Wrong!
The correct answer is C. 44.1 kHz.
A sampling rate is the number of times per second that a continuous signal is measured. The higher the sampling rate, the more accurate the representation of the signal will be. For CDs, the sampling rate is 44.1 kHz, which means that the signal is measured 44,100 times per second. This is enough to capture all of the frequencies that are audible to humans.
Option A is incorrect because it is not a valid sampling rate. Option B is incorrect because it is the sampling rate for cassette tapes. Option D is incorrect because it is the sampling rate for DVDs.
