Radio frequency refers to the compression of images and sounds into a certain high-frequency signal for transmission, and then the images and sounds are transmitted to the screen and speakers respectively through decompression and separation after receiving.
Radio Frequency (RF) is the abbreviation of radio frequency, which means electromagnetic frequency that can radiate into space, and the frequency range is from 300 kHz to 300 GHz. Radio frequency is abbreviated as RF current, which is the abbreviation of high frequency AC electromagnetic wave. Alternating current that changes less than 1000 times per second is called low-frequency current, and that that changes more than 10000 times is called high-frequency current, and radio frequency is such high-frequency current. High frequency (greater than10k); Radio frequency (300K-300G) is the higher frequency band of high frequency; Microwave band (300M-300G) is the higher frequency band of radio frequency.
