WebbRadiofrequency ablation is a method of destroying tumors with heat caused by the friction of ions in the tissue under the influence of high-frequency alternating current, located in the range of sound waves. Accordingly, an electrode is placed in the center of the tumor and maintained at a destructive temperature of 60 -100°C. WebbThese radio waves travel over line of sight, making them ideal for local communications over a few kilometres. Indeed, UHF radio frequencies best suit communications within a one kilometre radius – perfect for indoor applications. What are the benefits of HF radio vs VHF/UHF radios? Each mode of radio wave propagation is useful in different ... WebbThis high frequency wave (Radio frequency wave) is transmitted in space through antenna. At the receiver end, the audio signal is extracted from the modulated wave by the process called demodulation. The audio signal is then amplified and reproduced into sound by the loud speaker. A high frequency radio wave is used to carry the audio signal. bot1200-96s
