What Is The Difference Between Am And Fm Radio

These both techniques are widely used for broadcasting the radio signals that are transmitted in the form of electromagnetic waves.

Am waves work in the range of khz while in fm waves work in mhz range. First off am and fm broadcast on very different frequencies. Fm radio was developed in the united states mainly by edwin armstrong in the 1930s. Am waves are much longer than fm while fm waves have much higher frequencies.

Due to the much better transmission quality most music radio stations prefer fm over am to transmit information mostly songs to their listeners. Well for starters am and fm are means of sending information through airwaves which people listen over their radios. Am versus fm mode of modulation. Am stands for amplitude modulation and fm stands for frequency modulation.

Now what is this modulation. 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. Am stands for amplitude modulation while fm means frequency modulation.

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. 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. Radio waves are limited in how far they can be transmitted.

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. There are basic differences between the two apart from the fact that transmission using fm is much clearer than that of am. 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. Fm signals have low reception coverage which limits them to cities and neighboring areas.

Am waves traverse cities and remote areas alike reaching far more people than fm. Wavelength difference between am and fm. Differences in spectrum range.
