InSb etalons operated at 77 K and illuminated by CO lasers (5.5 μ m) exhibit continuous wave (c.w.) optical bistability. A wide range of experiments have been performed to further the basic ...

Digital design with combinatorial gates like AND, OR, and NOT gates is relatively straightforward. In particular, when you use these gates to form combinatorial logic, the outputs only depend on the ...

A hybrid computer uses rotating mechanical beams for memory and electrical contacts for logic, performing reprogrammable computation through physical motion in environments where conventional ...

All modern digital logic consists of combinatorial logic and sequential logic. Combinatorial logic is made up of gates while sequential logic comprises of flipflops. Different transistors are ...

Researchers have created logic gates – the building blocks of digital circuits – by using a combination of a novel fluorescent probe, DNA molecules and specific enzymes 1. Such logic gates may be ...

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...
