• ### Limits to Amplification

Publication Year: 1934, Page(s):1449 - 1454
Cited by:  Papers (5)
| | PDF (1476 KB)

The amplification obtainable in a vacuum tube amplifier is limited by the noise in the circuit. Of the various sources of noise the most fundamental and inevitable is thermal agitation of electricity. Other sources are the influence of ions and of shot effect and flicker effect on the current in vacuum tubes, poor contacts, mechanical vibration, and hum from a-c cathode heating. These noises and t... View full abstract»

• ### Power Losses in Induction Machines

Publication Year: 1934, Page(s):1466 - 1471
Cited by:  Papers (4)
| | PDF (1429 KB)

Losses in induction machines have been subjected to a detailed study by many investigators, but due to the complex nature of some of these losses, particularly several forms of load loss in induction motors, a clear understanding of their nature, has not been available. Since the majority of such losses are connected with the magnetic flux in the machine, a study of the distribution of magnetic fl... View full abstract»
