After the antennas have been excited by these currents, they start radiating radio waves. Transmitters are additionally utilized for the purposes of broadcasting and are vital equipments of communication that utilizes radio technologies (Rider, 2008). This includes equipment like cell phones, Bluetooth along with computer networks that utilize wireless technology. Transmitters are usually limited to use in equipments that are used for generating radio waves for the purpose of enabling communication (Uhrig, 2006).
There are mainly three types of transmitters which are the beltpack, plug-in and handheld transmitters. The design of beltpack transmitters shows that they should be placed on the user’s body and is normally used with the help of a microphone situated outside the electronic device. They provide a lot of power to the electronic devices using batteries located on their inside (Brunetti, 2009). The plug-in type of transmitter on the other hand is made so that it can be inserted into standard dynamic microphones through their connectors. The plug-in transmitters are commonly utilized by television crews that are carrying out activities in the field. Lastly, the handheld transmitters combine microphone elements along with transmitters that have been built into one assembly line. ...Show more
