Once the schematic has been made, it is converted into a layout that can be fabricated onto a printed circuit board (PCB). Schematic-driven layout starts with the process of schematic capture. The result is what is known as a rat's nest. The rat's nest is a jumble of wires (lines) criss-crossing each other to their destination nodes.
This is a list of vacuum tubes or thermionic valves, and low-pressure gas-filled tubes, or discharge tubes. Before the advent of semiconductor devices, thousands of tube types were used in consumer electronics.
This tube is a Novar tube. It has the same physical dimensions as the compactron, but a 9 pin base. The exhaust tip is on the top or bottom of the tube, depending on the manufacturer's preference. It is currently in production by Electro-Harmonix.(The new power amp, Linear Tube Audio's Ultralinear, uses 4 17JN6 compactron tubes as the power ...

In USSR, glow-discharge stabilitrons were given designation in Cyrillic with serial number of development. [2] For example, "СГ21Б", "СГ204К" and i.e. [2] VR tubes were only available in certain voltages. Common models were: Octal-based tubes, 5–40 mA current: [3] 0A3 – 75 volts; 0B3 – 90 volts; 0C3 – 105 volts (best regulation of ...
These experimental designs (all of which shared the BWR-1 classification despite their divergent designs) used fuel rod bundles in 6×6, 7×7, 8×8, 9×9, 11×11, and 12×12 configurations, but GE's 9×9 bundle later used in BWR/2–6 reactors is different from the one used in the BWR/1 era. [2]
A transmission gate (TG) is an analog gate similar to a relay that can conduct in both directions or block by a control signal with almost any voltage potential. [1] It is a CMOS -based switch, in which PMOS passes a strong 1 but poor 0, and NMOS passes strong 0 but poor 1.
