How Radio technology works and What are the applications of radio remote control?
Radio waves are used to control any type of equipment and machines wirelessly, such kind of a control system is called a Radio Remote Control . Here is the detailed information on how radio technology works? The signal transmitted or received by the antenna If the transmitter transmits the signal or the receiver picked up the signal, a bandpass filter allows only desired frequency and attenuates the other frequency signal. While Radio waves passing through an air medium, there are many different RF waves are present so, the antenna tuned the required frequency and receives the specific signal. For selecting the length of the antenna, the formula is λ = c/f where λ = wavelength C = Speed of light F = desired frequency ...
