It may be said that radio interference and its correction arose with the first spark-gap experiment of Marconi in the late 1800s. [3] As radio communications developed in the first half of the 20th century, interference between broadcast radio signals began to occur and an international regulatory framework was set up to ensure interference-free communications.
Electromagnetic interference divides into several categories according to the source and signal characteristics. The origin of interference, often called "noise" in this context, can be human-made (artificial) or natural.
The water molecule, in the gaseous state, has three types of transition that can give rise to absorption of electromagnetic radiation: Rotational transitions, in which the molecule gains a quantum of rotational energy.
