WebbNote that the value of S/N = 100 is equivalent to the SNR of 20 dB. If the requirement is to transmit at 5 mbit/s, and a bandwidth of 1 MHz is used, then the minimum S/N required is given by 5000 = 1000 log 2 (1+S/N) so C/B = 5 then S/N = 2 5 −1 = 31, corresponding to an SNR of 14.91 dB (10 x log 10 (31)). Channel capacity is proportional to ... George Boole presented this expansion as his Proposition II, "To expand or develop a function involving any number of logical symbols", in his Laws of Thought (1854), and it was "widely applied by Boole and other nineteenth-century logicians". Claude Shannon mentioned this expansion, among other Boolean identities, in a 1949 paper, and showed the switching network interpretations of the identity.

Webb6 apr. 2012 · Shannon's expansion is a method which breaks down these large functions into smaller functions. Boolean logic functions (F) can be expanded in terms of Boolean variables (A). We consider a function: • F (Sum) = A'B'C+A'BC'+AB'C'+ABC (Full Adder) Split the above function (F (Sum)) into two smaller functions: • F = A (B'.C'+B.C)+A' (B'.C+B.C') Webb17 nov. 2024 · Shannon’s expansion theorem is used to achieve the minimum implementation cost for the proposed XOR gate.
