Either of those methods, plus a few others, can be used
to add information to a radio wave.
Amplitude modulation.
FM means frequency modulation, and AM means amplitude modulation.
AM stands for amplitude modulation FM stands for frequency modulation
AM stands for amplitude modulation, while FM stands for frequency modulation. In AM, the amplitude (the height or depth of the crests or troughs) changes, while in FM, the frequency changes.
They could mean a lot of things, but in the context of each other they probably stand for Amplitude Modulation and Frequency Modulation (two different methods for sending an audio signal using radio waves) respectively.
FM means frequency modulation AM means amplitude modulation
A: AM radio is an Amplitude Modulation transmission . Meaning it has fix frequency but it is modulated by the signal. FM Frequency Modulation the frequency is modulated by the signal
AM stands for Amplitude Modulation. In theory, amplitude modulation could be applied to a radio signal on any frequency but the AM band on most domestic radios stretches from 530 to 1700KHz.

Amplitude Modulation (AM) and Frequency Modulation (FM) AM tuning changes the amplification size of the waves being received, FM tuning controls the frequency of the waves being received. As commercial radio rose from it's early form, the AM 'band' stood for years as the only type of radio available. As technology improved, engineers discovered that they could modulate 2 channels of higher quality sound inside of one carrier frequency. The Federal Communications Commission designated from 87 MHz to 108 MHz for the new FM format. And, with this, FM radio was born.
AM-Amplitude modulated FM-Frequency modulated Explanation: The frequency and amplitude refer to the width and height of wavelengths in the radio waves that are used to transmit the signal. FM is usually a better signal than AM because the frequency of the waves is less distorted than amplitude.
Aptitude Modulation means the height of the information changes the height of the signal in the radio frequency wave.
