how do they improve high-frequency transmission (and not low-frequency?) ?
I'm a biologist...
Thanks

Telephone loading coils are small devices that are used to improve the transmission of telephone signals over long distances. They are typically made of copper wire wound around a magnetic core, and are placed at regular intervals along telephone lines to compensate for signal loss.
The main purpose of telephone loading coils is to reduce transmission line losses, which occur when a signal travels long distances. These losses can distort and weaken the signal, resulting in poor call quality. Loading coils help to maintain the strength and clarity of the signal, allowing for better communication over long distances.
Telephone loading coils work by inductance, which is the ability of a coil to store energy and create a magnetic field. When a signal travels through a telephone line, it encounters resistance, which causes the signal to weaken. The loading coil acts as a booster, adding inductance to the line and helping to counteract the signal loss.
The use of telephone loading coils has several benefits, including improved call quality over long distances, increased transmission speeds, and reduced cost of laying new telephone lines. Loading coils also help to reduce crosstalk, which is when signals from different lines interfere with each other, resulting in clearer communication.
While telephone loading coils have many benefits, they can also have some drawbacks. Loading coils can introduce distortion to the signal, which can affect the quality of the call. Additionally, loading coils can only be used on analog telephone lines, so they are not compatible with digital or VoIP systems.
