Sampling may refer to: . Sampling (signal processing), converting a continuous signal into a discrete signal Sampling (graphics), converting continuous colors into discrete color components Sampling (music), the reuse of a sound recording in another recording Sampler (musical instrument), an electronic musical instrument used to record and play back samples

In some contexts, the signal bandwidth in hertz refers to the frequency range in which the signal's spectral density (in W/Hz or V 2 /Hz) is nonzero or above a small threshold value. The threshold value is often defined relative to the maximum value, and is most commonly the 3 dB point, that is the point where the spectral density is half its maximum value (or the spectral amplitude, in or ...

Aug 17, 2021 · Details of how the converter work are beyond the scope of this book. The key thing is the sampling rate, which is the number of times a second the converter takes a sample of the analog signal. Now, the sampling rate doesn’t really matter for us, as we are doing everything digitally, but it’s needed for our sine wave formula.
