WebbOne of the important architectural insights from information theory is the Shannon source-channel separation theorem. For point-to-point channels, the separation theorem shows that one can compress a source separately and have a digital interface with the noisy channel coding; and that such an architecture is (asypmtotically in block size) optimal. Webb27 juli 2024 · This is precisely the non-intuitive content of Shannon’s channel coding theorem. A similar result was derived by von Neumann where he showed that as long as the basic gates used in constructing a computer are more reliable than a certain threshold, one could make a highly precise computer. WebbShannon's source coding theorem has defined the theoretical limits of compression ratio.
