WebThe regenerative radio was developed by Edwin H. Armstrong and patented in 1914. [1] The receiver uses a single vacuum tube for both amplification and detection, utilizing positive feedback to both increase the gain from a single vacuum tube and to improve the selectivity of the receiver. [2] How it Works WebVacuum tubes have the same function as transistors. They are constructed like filament light bulbs. Inside an evacuated chamber, usually glass, they have glowing filaments and intricate metal screens and plates. The lightbulb-like filament is heated to incandescence to drive electrons off its surface.

WebThe vacuum tube voltmeter (VTVM) uses the high input impedance of a valve to buffer the circuit being measured from the load of the ammeter. Valve oscilloscopes share this very high input impedance and thus can be used to measure voltages even in very high impedance circuits. http://www.radioremembered.org/detector.htm

WebThe Triode. De Forest’s Audion tube came to be known as the triode tube because it had three elements: filament, grid, and plate (just as the “di” in the name diode refers to two elements: filament, and plate). Later developments in diode tube technology led to the refinement of the electron emitter: instead of using the filament directly ...
