I want to know the answer to the following question:
What is the name of the sampling theorem?
All the background I'm provided with is that "Because of the Nyquist–Shannon sampling theorem, frequency reproduction is always strictly less than half of the sampling frequency, and imperfect filters requires a larger margin for error (noise level versus sharpness of filter), so 8 kHz sampling rate limits the maximum frequency to 4 kHz, while 48 kHz maximum sampling rate limits an MP3 to 24 kHz sound reproduction.". Is that enough to answer the question?
Answer: yes
