The more common approach to manipulate the incoming AC wave so that both halves are used to cause output current to flow in the same direction is the use of full-wave rectifiers. A full-wave rectifier ...

Schemes of two-half-period rectifiers on op amps with switching inputs in accordance with the polarity of the input voltage are given. The switching of inputs is performed by a control signal taken ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Helium-filled half-wave rectifier. A 4-pin base with brass shell and ceramic insulator. Tipped S-shaped envelope. Maker's stamping on base reads: "Raytheon / Type B Patented / June 27, 1922 July 7, ...
