What Is The Difference Between Am And Fm Radio

Am radio ranges from 535 to 1705 kilohertz whereas fm radio ranges in a higher spectrum from 88 to 108 megahertz.

Radios pick up these different waves using different kinds of antennas and use different methods to turn am and fm waves back into recognizable sounds. There is a reason why you can t listen to your favorite music stations abroad. That is why am radio channels often face the problem where sound intensity varies while fm radio channels have constant good reception. Pros and cons of am vs.

While am and fm radio function and operate in the same ways and by the same principles the biggest difference between the two is the way in which the carrier waves are modulated. Am waves are much longer than fm while fm waves have much higher frequencies. Am radio am stands for amplitude modulation as am radio signals vary their amplitude to adapt to the sound information that is being broadcasted through the wavelengths. Well for starters am and fm are means of sending information through airwaves which people listen over their radios.

Now what is this modulation. Fm signals have low reception coverage which limits them to cities and neighboring areas. Differences in spectrum range. Radio waves are limited in how far they can be transmitted.

Due to the much better transmission quality most music radio stations prefer fm over am to transmit information mostly songs to their listeners. As a result am waves have a higher wavelength than the fm ones. There are basic differences between the two apart from the fact that transmission using fm is much clearer than that of am. As mentioned earlier am involves the alteration of the amplitude of the carrier wave whereas fm involves changes in the frequency of the carrier wave.

Am waves work in the range of khz while in fm waves work in mhz range. These both techniques are widely used for broadcasting the radio signals that are transmitted in the form of electromagnetic waves. For am radio stations are possible every 10 khz and fm stations are possible every 200 khz. Wavelength difference between am and fm.

Fm radio was developed in the united states mainly by edwin armstrong in the 1930s. Am stands for amplitude modulation while fm means frequency modulation. Am stands for amplitude modulation and fm stands for frequency modulation.
