Mutual Electromagnetic Perturbations-RF Measurements in the VHF and UHF Frequencies in Bucharest: Theoretical and Practical Aspects

The unprecedented development in the field of electronic and electrical systems with various destinations leads to an agglomeration of the electromagnetic spectrum, but also to the occurrence of interferences and disturbances that affects the normal functioning of the equipment, pollute the environment and affects the functionality of other users. This article highlights various types of electromagnetic disturbances in the RF (Radio Frequency) spectrum with some examples in daily practice. Different aspects of concentrated and dispersed reciprocal perturbations, harmonic secondary radiation, as well as explanation of the various intermodulation products are presented in examples.
