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 ...

Who would have thought that a circuit comprising only two 2-input NAND gates could be so complicated (or, should we say, “interesting”)? Up to this point (click here to see my earlier columns), the ...
