Using PCM with 8 … WebDec 11, 2024 · The central limit theorem helps in constructing the sampling distribution of the mean. The theorem is the idea of how the shape of the sampling distribution will be normalized as the sample size increases. In other words, plotting the data that you get will result closer to the shape of a bell curve the more sample groups you use.

Because such quality features cost money, many sound cards do not have anti-aliasing filters or, for that matter, post-sampling filters.

"The sampling theorem was implied by the work of Harry Nyquist in 1928, in which he showed that up to 2B independent pulse samples could be sent through a system of bandwidth B; but he did not explicitly consider the problem of sampling and reconstruction of continuous signals. About the same time, Karl Küpfmüller showed a similar result and discussed the sinc-function impulse response of a band-limiting filter, via its integral, the step-response sine integral; this bandlimitin… " - Example of sampling theorem

WebClearly the sampling rate must be high enough to give a faithful representation of the applied signal. Nyquist's theorem states that a periodic signal must be sampled at more than twice the highest frequency component of the signal. In practice, because of the finite time available, a sample rate somewhat higher than this is necessary. http://www.dspguide.com/ch3/2.htm
