With the help of a diagram, show how you can use several NAND gates to obtain an OR gate.
Useful Constants and Relations :
|1. Speed of Light in Vacuum||(c) = 3.00 x 108 m/s|
|2. Charge of a proton||(e) = 1.60 x 10-19C|
|3. Planck's Constant||(h) = 6.6 x 10-34 Js|
|4. Permeability of vacuum||(μ0) = 4π x 10-7 Hm-1|
|5. Electron Volt||(1eV ) = 1.6 x 10|
|6. Unified Atomic Mass Unit||(1u) = 931 MeV|
|(π) = 3.14|
|( ln 2 ) = 0.693|
In the figure is shown an ‘OR’ gate produced by combining ‘NAND’ gates only.
