Pulsed-modulated fields are electromagnetic fields generated through a periodic sequence of non-harmonic pulses. These pulses have a specific frequencyThe frequency describes the number of oscillations per second and is given in the unit Hertz (Hz). An oscillation passes through various points: The starting point, the maximum point, the... and amplitude and are used, for example, in telecommunications. They are generated with specific frequencies and intensities and can be both low-frequency and high-frequency. Pulse-modulated fields can have both positive and negative effects on the human body, so their use should be carefully regulated.
