FM means frequency modulation AM means amplitude modulation
Aptitude Modulation means the height of the information changes the height of the signal in the radio frequency wave.
Amplitude Modulation- the AM band , commercially, is in kilocycles.
modulation within a composition can help define the
amplitude modulation & frequency modulation
In amplitude modulation, modulation depth refers to the ratio of the unmodulated carrier amplitude to the amplitude deviation for which the modulated carrier wave reaches its minimum value. If this minimum value is zero, the modulation depth is 100%.For amplitude modulation,modulation depth = (a-b)/(a+b),wherea is the unmodulated carrier amplitude, andb is the minimum amplitude deviation.The modulation depth ratio is also referred to as the modulation index.

Modulation index is also called as Modulation depth. The modulation index of a modulation scheme describes by how much the modulated variable of the carrier signal varies around its unmodulated level.
FM means Frequency Modulated.FM stands for modulation on frequency or frequency modulation.
我不知道-look it up
FM means frequency modulation AM means amplitude modulation
FM means frequency modulation, and AM means amplitude 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.
AM means 'amplitude modulation'
Modulation is any of several means of encoding an information carrying signal onto a carrier of fixed frequency. The purpose is to allow the information to be transported long distances.
It means modulation of the voice or tone of your words.
