The other form of electromagnetic is radiation, where radiation is a wireless transmission which is obtained by the energy through space. The usage of this radiation is been utilized in many ways such as they can carry big amount of information which includes sound, radioactive waves, amplitude of these waves and phase width. The working of these waves are being used in such a manner where the radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information can be extracted and transformed back into its original form.
The transmission of the radio system need to modulate(change) some property of energy produced to impress a signal on it, The examples can be by using modulation, angle modulation ( which can be frequency modulation or phase modulation).Radio systems also need an antenna to convert electric currents into radio waves, and vise versa. These antenna need to convert electric current into radio waves. Antenna can be used to both transmitting and receiving. The selection of these electrical resources of tuned circuits in radios allows individual stations to be selected. This electromagnetic wave is intercepted by a tuned receiving antenna.
About the Jensen company
There is a brand known as Jensen brand which is popular for electronics and stuff. The history of this brand started in 1915 with the invention of a loudspeaker by the scientist named Peter Jensen. It is a matter of a lot of years that the family of Jensen having different brands has been such that it grew to include the company of Jensen in America. There are a lot of products related to electronics that are manufactured by the brand of Jensen. In the mid of the decade of 1980s, there were a lot of changes in the company and all.
There are a lot of different types of radios and there are a lot of different companies that manufacture their radios. There are different features available in the radios for different companies. Jensen radios are one of the famous radios of the present age.
