RF Modulator
Radio frequency Modulator or RF Modulator is very important for transmission of waves over a long distance. Generally, when long distance signal transmission happens, it suffers a great deal of disturbance. Here, these RF modulators mingle the signal along with some other high frequency wave for better transmission. These RF modulators are present in modern day communicating devices for serving the purposes efficiently.
The RF modulator transforms the signal to be transmitted through long distance and then demodulates again when it reaches the other end. This demodulation is done at the receiving end. RF modulator is a very essential constituent in all the RF transmitters like play stations, DVD players etc. The RF cable enables the transfer of signal from these gadgets to television and it affects the picture and sound quality to a large extent. RF modulators are in great use everywhere, including areas like aviation and defense sectors for transmitting information.
