Diode Logic Gate Versions
In logic gates, logical functions are performed by parallel or series connected switches controlled by input logical variables. In diode logic, electrically operated switches are implemented by diodes: when forward biased, a diode switch is closed; when backward biased, the switch is open. There are two kinds of diode logic gates - OR and AND. It is not possible to construct NOT diode gate. The explanations below are true for positive logic (high voltage represents logical 1 and low voltage represents logical 0).

Famous quotes containing the words logic, gate and/or versions:
“You can no more bridle passions with logic than you can justify them in the law courts. Passions are facts and not dogmas.”
—Alexander Herzen (1812–1870)
“What heaven-entreated heart is this
Stands trembling at the gate of bliss;
Holds fast the door, yet dares not venture
Fairly to open it and enter?
Whose definition is a doubt
‘Twixt life and death, ‘twixt in and out?”
—Richard Crashaw (1613?–1649)
“The assumption must be that those who can see value only in tradition, or versions of it, deny man’s ability to adapt to changing circumstances.”
—Stephen Bayley (b. 1951)
