Symbol for an OR gate. The Boolean algebra expression used to define an OR gate is (6)X=A+B. The “+” sign denotes the “OR” operation rather than the usual addition. This equation is read, “The output X is true (or equal to 1) when either input A OR input B is true (or...

The addition of two digits gives a sum and a carry. This is normally carried out as sum = A.B + A. B, and Carry = A.B. The former requires two NOT gates two AND gates and one OR gate or eight transistors. The application proposes a two transistor EITHER gate or EXCLUSIVE-OR ...
A logic-gate system with three outputs and three inputs was developed based on the bioelectrocatalysis of glucose by glucose oxidase (GOx) entrapped in chitosan films on the electrode surface by means of ferrocenedicarboxylic acid (Fc(COOH)2). Cyclic voltammetric (CV) signals of Fc(COOH)2 exh...

In summary, for the first time we created a two-input logic OR gate in a single protein through allosteric regulation by combining two orthogonal regulators. The architecture presented in this work can be extended to other proteins. We envision that this approach will pave the way for constructi...
Their compositions and structures were characterized by elemental analysis, IR, UV-vis and fluorescence spectra. The fluorescence of Al(DPP-PA)3 was quenched by the addition of Fe3+, and the INHIBIT logic gate was fabricated.关键词:diketone metal complex fluorescence switch INHIBIT logic gate ...

Here, we introduce an amplitude modulator and theoretically demonstrate an enhanced on/off ratio of a DLP logic gate for XNOR operation. Multimode interference (MMI) in DLP waveguide is precisely calculated for the design of the logic gate. Multiplexing and power splitting at arbitrary multimode ...
