What does AM and FM stand for in radios?
AM - Amplitude Modulation FM - Frequency Modulation
What does am frequency stand for?
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.

What is Modulation index in Frequency modulation?
Modulation Index is the ratio of the maximum deviation frequency to the frequency of modulation. In other words it is the ratio of the spread in frequency spectrum to the frequency that was used to modulate the carrier. For FM, modulation index is given by the formula mf= df/f where, mf=modulation index for FM df=difference in carrier frequency f=frequency of the signal
550khz-1610khz is frequency range of which modulation system?
This frequency range is used for A.M Radios specifically M.W(Medium Wave) Band. More information of MW band will be on http://en.wikipedia.org/wiki/Medium_wave
What does FM stand for in radio frequency?
FM means Frequency Modulated.FM stands for modulation on frequency or frequency modulation.
What is FM?
FM stands for frequency modulation. The definition is: when the frequency of the carrier wave is changed in accordance with the intensity of the signal, it is called frequency modulation. In frequency modulation, only the frequency of the carrier wave is changed in accordance with the signal. However, the amplitude of the carrier wave remains unchanged.
What is the difference between frequency modulation and phase modulation?
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
What is the meaning of FM in FM Radio?
FM means frequency modulation AM means amplitude modulation
What is the difference between am radios waves and FM radio waves?
AM means Amplitude(=height) modulation, so the frequency stays the same and the message is coded into variations of the strength of the signal. FM stands for Frequency modulation. Here the strength of the signal stays the same and the message is coded into changes in frequency instead.
What is the relationship between frequency modulation and the frequency carrier to the modulation index in the AM modulation?
fc>2fm
When modulation frequency is double the modulation index is halF and the modulating voltage remains constant the modulation system is?
frequency modulation..
