Frequency modulation have some advantages over amplitude modulation, FM is not sensitive to the amplitude noise, and have high efficient use of transmitted power
AM - Amplitude Modulation FM - Frequency Modulation
Normal frequency range for amplitude modulation is 550kHz to 1610kHz
am is amplitude modulation, fm, frequency modulation
because noise usually changes the amplitude not frequency.
Amplitude of the (high frequency) Carrier signal is varied with respect to low frequency of message signal is called amplitude modulation. Frequency of the carrier signal is varied with respect to low frequency of message signal is called frequency modulation.
Amplitude Modulation (AM) Frequency Modulation (FM)
amplitude modulation
amplitude modulation & frequency modulation
amplitude modulation is where we modulate our signal with a carrier signal amplitude changes but frequency remains constant in amplitude modulation
the frequency range of an am wave is 20herz to 20kilo herz
AM = Amplitude Modulation. FM = Frequency Modulation
