The Heaviside condition is that the series impedance, Z, must be proportional to the shunt admittance, Y, at all frequencies. The mathematical condition for distortion-free transmission is known as the Heaviside condition. This is the condition that must be fulfilled in order for a transmission line to be free from distortion. By applying his operational calculus to the analysis of this network he discovered (1887) what has become known as the Heaviside condition. Heaviside was aware that this condition was not met in the practical telegraph cables in use in his day. Consequently, between that day and this, a splendid system of cables has been built up between ourselves and India. The CAN bus protocol is widely implemented due to its fault tolerance in electrically noisy environments such as model railroad sensor feedback systems by major commercial Digital Command Control system manufacturers and various open-source digital model railroad control projects. Using different pins allows for full-duplex communication, in which information can travel in both directions at once. Submarine communications cables are particularly subject to the problem, but early 20th century installations using balanced pairs were often continuously loaded with iron wire or tape rather than discretely with loading coils, which avoided the sealing problem.

1894, filed December 1893) which is sometimes cited as Pupin's loading coil patent but is, in fact, something different. This increases the flux linkages, without which the number of turns on the coil would need to be increased. The CAN standard was devised to fill this need. It would need costly stations to be built at Mauritius, Rodrigues, Cocos, and Perth on the way. Heaviside considered, but rejected, this possibility which left him with the strategy of increasing L as the way to reduce distortion. Finally, Heaviside made the proposal (1893) to use discrete inductors at intervals along the line. The term is also used for inductors in radio antennas, or between the antenna and its feedline, to make an electrically short antenna resonant at its operating frequency. The coil is built to have an inductive reactance equal and opposite to the capacitive reactance of the short antenna, so the combination of reactances cancels. The loading coil is often placed at the base of the antenna, between it and the transmission line (base loading), but for more efficient radiation, it is sometimes inserted near the midpoint of the antenna element (center loading). A loading coil or load coil is an inductor that is inserted into an electronic circuit to increase its inductance.

Because twisted pair is a balanced format, half the loading coil must be inserted in each leg of the pair to maintain the balance. Despite the use of common cores, such loading coils do not comprise transformers, as they do not provide coupling to other circuits. A common application of loading coils is to improve the voice-frequency amplitude response characteristics of the twisted balanced pairs in a telephone cable. Campbell was tasked with continuing the investigation into Stone's bimetallic cable, but soon abandoned it in favour of the loading coil. Stone's idea (1896) was to use a bimetallic iron-copper cable which he had patented. The very first demonstration of loading coils on a telephone cable was on a 46-mile length of the so-called Pittsburgh cable (the test was actually in Boston, the cable had previously been used for testing in Pittsburgh) on 6 September 1899 carried out by Campbell himself and his assistant.

The bulge of the loading coils could not easily pass through the cable laying apparatus of cable ships and the ship had to slow down during the laying of a loading coil. You must examine the control cables and choose a control cable with technically superior specifications, to receive an error-free performance throughout. Unlike cable TV, which requires the installation of physical cables and set-top boxes, NowTV can be accessed through various devices such as smartphones, tablets, smart TVs, or streaming devices like Roku or Apple TV. To reduce losses due to high capacitance on long-distance bulk power transmission lines, inductance can be introduced to the circuit with a flexible AC transmission system (FACTS), a static VAR compensator, or a static synchronous series compensator. In countries that have traditionally used NTSC System M, the sections are 52-1000 MHz for forward-path signals, and 5-42 MHz for return-path signals. ATX allowed each motherboard manufacturer to put these ports in a rectangular area on the back of the system with an arrangement they could define themselves, though a number of general patterns depending on what ports the motherboard offers have been followed by most manufacturers. Intervals of a kilometer allowed European systems to carry 2 Mbit/s.
