Radio-Electronics
1. The electron was discovered more than fifty years ago, but has never been seen.
2. In this type of receiver a crystal detector is followed by an audio amplifier.
3. Some circuits are effected by changes in line voltage.
4. The distribution of the flux is influenced by the frequency of the flux and the resistance of the coil.
5. Most electronic devices are enclosed in glass tubes from which the air has been pumped out.
6. Semiconductor devices which are being used to help electron valves reduce the size of instruments considerably.
7. The receiver has been developed to illustrate the principle of molecular electronics.
8. Electronics is defined in an English dictionary as “the study of conduction of electricity in a vacuum, in glass and in semiconductors.
9. An unusual group of crystalline semiconductors, which in spite of the presence of various admixtures preserve their basic properties and electrical conductivity have been discovered.
10. The distance to the object is being calculated from the elapsed time between the transmitted pulse and the received echo.
11. An analytical solution is provided to any desired order in terms of multifold convolution integrals of the Fourier transform of the impedance function.
12. A physics–based methodology is being considered to develop and advance scattering models for various terrain and environmental features.
13. In this paper an analytical formulation is developed to predict the diffraction from a surface impedance discontinuity of an arbitrary profile.
14. Geometrical theory of diffraction models has only been applied to problems where abrupt variations in a surface are present.
15. A solution is sought for problems with a more general variation across the diffraction surface with arbitrary dimensions compared to the wave length.
16. All pads are protected against damage from electrostatic discharge and from over–voltage transients.
17. An integral equation for an impedance surface is formulated in the Fourier domain, which is solved iteratively using a perturbation technique.
18. The theory of electromagnetic waves were predicted from the research of James Clerk Maxwell and Michael Faraday.
19. The experiments were not followed up by Hertz and the practical applications of the wireless communication and remote control technology were implemented by Nikola Tesla.
20. The term is commonly used in the telecommunications industry to refer to telecommunications systems
