What Do AM and FM Stand for

What are AM and FM:

AM and FM, in the world of broadcasting, are acronyms that relate two ways of modulating the carrier of electrical signals. I AM corresponds to the initials of ‘modulated amplitude’, while FM means ‘frequency-modulated’.
AM or amplitude modulated

AM means amplitude modulated or amplitude modulation, is a technique used in electronic communication that is to vary the amplitude of the wave radio frequency carrier. As such, it was the first technique that was used to do radio.

The AM channel has a bandwidth which lies between 10 KHz and 8 kHz due that are more low frequencies whose wavelengths are over, the range of your signal is considerably broader in relation with the modulated frequency.

In this sense, AM waves can be measured between 100 meters (3000 KHz) and 1000 meters (300 KHz). This is the kind of wave that reaches the ionosphere and bounce in it.

However, the sound quality of the amplitude modulated (AM) is well below the the frequency modulated (FM). In addition, as it is of low frequency waves, they are more vulnerable to noise, because these are produced in the amplitudes of the waves. In spite of this, is the most advisable wave for mountainous areas.

FM or frequency modulation

FM modulated frequency means; it is a technique that allows you to transmit information through a carrier wave by varying its frequency. As such, it was patented in 1933 by the American inventor Edwin Howard Armstrong.

Frequency-modulated channel has a bandwidth of 200 KHz. similar width allows the transmitted sounds (music and speech) have higher fidelity and quality, and are more clean and clear in the modulated amplitude.

In frequency modulation, a station transmits on 101.1 MHz (i.e., 101.100 KHz), and this does so at 101.3 MHz (i.e. 101.300 kHz). This means that you between a channel and another remain free 200 KHz. In addition, allows to send double signal, i.e., a stereo signal.

However, the scope of frequency-modulated signals is lower than the modulated amplitude. This is because the frequency-modulated transmitted between 88 and 108 MHz, i.e. very high frequencies, whose waves can be measured between one meter (300 MHz) and ten meters (30 MHz). This type of waves, in addition, have considerably small lengths, so that move in a straight line and are attenuated rapidly. There is a type of wave ideal for flat areas, where the waves can be transmitted without hindrance.
