On the transmission capacity of the ‘ ether ’ and of cables in electrical communications

چکیده
In 1933 the young Russian communications engineer Vladimir Aleksandrovich Kotelnikov published a paper in which he formulated the sampling theorem for lowpass and bandpass signals, and also considered the bandwidth requirements of discrete signal transmission for telegraphy and images. Although Kotelnikov’s name later became known in the West as a result of his subsequent work, particularly that on optimal detection, his pioneering 1933 results received little attention at the time outside Russian-speaking areas.

Changes in signal transmission speed in coaxial cables through regulating the foam structure of the polyethylene dielectric section
Polyolefins have been widely used in the electrical insulation and cable industry in recent years. One of the main usages of these materials is dielectric insulation in coaxial cables. Low attenuation and high signal transmission speed are among the desired features in coaxial cables. The role of polyethylene foam on signal transmission speed in the coaxial cables is the main focus of this stud...
متن کاملElectrical and Thermal Analysis of Single Conductor Power Cable Considering the Lead Sheath Effect Based on Finite Element Method
This paper investigates the effect of metallic sheaths on losses and temperature of medium voltage power cables. Two grounding methods of sheaths, including both ends bonding and single point bonding that causes different situations on cable ampacity, are considered. Electrical losses of cables that are main sources of heat are calculated in both conductor and metallic sheath of the cables. She...
متن کاملStability Analysis and Robust PID Control of Cable Driven Robots Considering Elasticity in Cables
In this paper robust PID control of fully-constrained cable driven parallel manipulators with elastic cables is studied in detail. In dynamic analysis, it is assumed that the dominant dynamics of cable can be approximated by linear axial spring. To develop the idea of control for cable robots with elastic cables, a robust PID control for cable driven robots with ideal rigid cables is firstly de...

متن کاملSecrecy of Communications in Data Transmission by Impulses with Unknown Moments of Appearance and Disappearance
We carried out a comparative analysis of the algorithms for detecting a rectangular impulse against Gaussian white noise under either authorized or unauthorized access to the transmitted data. We presupposed that for data transmission the binary communication system is used and that the useful information in the data is whether the signal is present or absent. The case is that unauthorized acce...
