The range of AM modulation ranges from, 535 to 1705 KHz or up to 1200 bits per second.
Normal frequency range for amplitude modulation is 550kHz to 1610kHz
The modulation index in AM can range from zero to any number. But if distortion is to be avoided, then the index must not exceed 100%.
modulation is necessary for transmitting low frequency signal to long range with desired qualitative information
The frequency range of FM signal is 88hz to 108hz.
Frequency modulation is not used for long distance transmission because it has the problem of limited band width.
Frequency modulation is used to broadcast radio waves to receivers. The most common use of it is in FM radio, which contains a range of radio frequencies.
the frequency range of an am wave is 20herz to 20kilo herz
AM (Amplitude Modulation) has a smaller bandwidth and can have more stations available in any frequency range. AM is cheaper and can be transmitted over long distances. FM (Frequency Modulation) signals are prone to interference due to physical obstructions. The better sound quality is due to a much higher bandwidth, using FM.
