Mathematics searches for new theorems to build upon the old. Engineering builds systems to solve human needs. The three disciplines are interdependent but distinct. Very rarely does one individual simultaneously make central contributions to all three — but Claude Shannon was a rare …

WebbWe won’t state Shannon’s theorem formally in its full generality, but focus on the binary symmetric channel. In this case, Shannon’s theorem says precisely what the capacity is. It is 1 H(p) where H(p) is the entropy of one bit of our source, i.e., H(p) = … WebbShannon ‘s 1949 definition: A cipher provides perfect secrecy against a ciphertext-only attack if the plaintext and the ciphertext, considered as random variables, are …

Then we will look at an explicit (and very “hands-down”) construction of a code due to Elias [1] that achieves a positive rate for some …
WebbNyquist'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. A sample rate of 4 per cycle at oscilloscope bandwidth would be typical. WebbThus, analogously to Theorem 10, we see that the expectation of the algorithmic mutual information I(x: y) is close to the probabilistic mutual information I(X; Y).. Theorems 10 …
