Solid Conductor

Solid Conductor: Electron Motion and Hole Transfer-Solid Conductor occurs in any given material when an applied voltage causes electrons within the material to move in a desired direction. This may be due to one or both of two processes; electron motion and hole transfer. In electron motion, free electrons in the Solid Conductor band are moved […]

Bandwidth Usage

Bandwidth Usage: It is reasonable to expect that the frequency range (i.e., bandwidth) required for a given transmission should depend on the Bandwidth Usage occupied by the modulation signals themselves. A high-fidelity audio signal requires a range of 50 to 15,000 Hz, but a bandwidth of 300 to 3400 Hz is adequate for a telephone […]

Need of Modulation

Need of Modulation: Need of Modulation – Until the process of superimposing a low-frequency (long-wave) voice information component on a high-frequency (short-wave) carrier signal was perfected, the most widely used form of communications was a system based on the transmission of a continuous-wave (CW) signal. With this system, the signal was interrupted periodically (Morse code) […]

Future Development of Electric Company Utilization

Future Development of Electric Company Utilization: As this is being written the whole energy field is so clouded in uncertainties that it would be foolish to attempt any quantitative predictions for the future. However, certain trends are discernible that will control the developments of the Electric Company Utilization in the decades ahead. Present Generation Mix […]

Voltage Structure of Energy Electric System

Voltage Structure of Energy Electric System: An Voltage Structure of Energy Electric System, even the smallest one, constitutes an electric network of vast complexity. The one factor that determines the system structure more than any others is system size. We shall not here enter into a discussion of the reasons of economical, political, historical, and […]
