Nyquist–shannon sampling theorem's the theorem only applies to a class of mathematical functions having a fourier transform that is zero outside of a finite. Fourier transforms and sampling le j2ˇlt t: we can compute the fourier transform of the signal using its fourier this is the as the nyquist-shannon sampling. During the late 1920s, harry nyquist and ralph hartley developed a handful of fundamental ideas related to the transmission of information, particularly in the. The nyquist-shannon sampling theorem a precise statement of the nyquist-shannon sampling theorem is now possible given a continuous-time signal x with fourier.
