Do semiconductors inherently digitize the sound?

Abstract What’s interesting to note is the random quantization of the pulse bursts (in a vacuum tube operated in ‘cold cathode’ mode). Does crystalline lattice semiconductor, operating a lower voltage due to direct surface contact and coupling, suffer similar quantization bursts of current flow?  Guitar amplifier legend Howard Dumble spoke of the “crystalline lattice” having … Read more

Speed of Light and Velocity of Electricity

Transformers contain many meters of wire.     https://www.youtube.com/watch?v=2Vrhk5OjBP8     The speed of light in a vacuum, denoted by the symbol “c,” is approximately 299,792,458 meters per second (m/s) or about 186,282 miles per second (mi/s). This speed represents the maximum velocity at which information or energy can propagate through space according to the … Read more

Fibrous magnetic fields

“Experiment has indicated that a magnetic field does possess a fibrous construct. By passing a coil of wire thru a strong magnetic field and listening to the coil output in headphones, the experimenter will notice a scraping noise. J. J. Thompson performed further experiments involving the ionization of gases that indicate the field is not … Read more
