In an 1886 letter, Charles Sanders Peirce described how logical operations could be carried out by electrical switching circuits.
12.
However, pulses from a controlled switching circuit often approximate the form of a rectangular or " square " pulse.
13.
Claude E . Shannon introduced the use of Boolean algebra in the analysis and design of switching circuits in 1937.
14.
Absent that, we are left with the ballast, the starter, the socket, or a temporary open in the switching circuit.
15.
Square waves are universally encountered in digital switching circuits and are naturally generated by binary ( two-level ) logic devices.
16.
Gallium arsenide, the primary chemical compound of gallium in electronics, is used in microwave circuits, high-speed switching circuits, and infrared circuits.
17.
Care should usually be taken when switching circuits to remove any metals from a person's body, to hold their breath and close their eyes.
18.
In 1886, he saw that logical operations could be carried out by electrical switching circuits, an idea used decades later to produce digital computers.
19.
The Baker clamp is named for Richard H . Baker, who described it in his 1956 technical report " Maximum Efficiency Switching Circuits ."
20.
Claude Shannon's 1938 paper " A Symbolic Analysis of Relay and Switching Circuits " then introduced the idea of using electronics for Boolean algebraic operations.
