457. Regenerative Vacuum
A simple vacuum tube receiver 5et .-- operation of a vacuum tube detector receiving set a simple way to work is this: when the filament is heated to the glory it gives off electronic mentioned above. Now, when the waves of the overhead lines, they set up the vibration of it, and loose coupling by tuning the coil primary coil Surge, a diagram is shown in Figure B. Glance that these oscillations of energy settings seeondary coil the same frequency and voltage of these high-frequency current is the first positive, then negative, in the closed circuit including the coil and variable capacitor seeondary surge oscillation. Alternately at the same time the oscillation of positive and negative impression of the grid voltage current in each switch from + to - and then return it to allow the electronic strike plate, and then close them off; in electronic form between filament larger plate from the B battery current path is detected to allow direct flow vacuum tube regenerative receiver and headphones.Operation a Set. by the feedback directly from the B cell pulse current through the coil it creates in the party scratching seeondary other stronger oscillation coil , the detector tube method, increase the sensitivity to a significant degree. Regeneration, or feedback, the receiver circuit will be easily understood with reference back to the action figure to the B. 47.
