Webhow invisible radio waves make so many things possible! The Simplest Radio By tapping the terminals of a 9-volt battery with a coin, you can create radio waves that an AM radio can receive! Radio can be incredibly simple, and around the turn of the century this simplicity made early experimentation possible for just about anyone. AM stands for Amplitude Modulation, and FM stands for Frequency Modulation. Both AM and FM radio programs are transmitted over the air via radio waves, which are part of a range of electromagnetic waves that include gamma rays, x-rays, ultraviolet rays, visible light, infrared, and microwave. Electromagnetic waves … Ver mais Electricity in the air is random noise. To be turned into useful signals that transmit information (music or voice), electricity must first be modulated. Therefore, modulation is the basis for AM and FM radio signals. Another … Ver mais AM radio uses amplitude modulation, the simplest radio broadcast form. To understand amplitude modulation, think about a steady signal (or wave) broadcasting at 1,000 … Ver mais FM radio uses frequency modulation. To understand frequency modulation, consider a signal with a steady frequency and amplitude. The signal's frequency is unchanged or unmodulated, so there's no useful information … Ver mais

An AM/FM receiver has both 455KHz and 10.7KHz tuned circuits in its IF stages, allowing it to work equally well for both bands. In fact, if you mix two frequencies f1 and f2, you get not only f1 - f2 but also f1 + f2.

WebAM only and AM/FM radios contain a number of tuned circuits which are adjusted by the manufacturer to the same frequency or frequencies by means of trimmer capacitors having an adjustable screw head, or by coils (often in an aluminium can) with a ferrite core that can be screwed in or out.
