What else can I help you with?
Amplitude modulation and frequency modulation range in India?
Normal frequency range for amplitude modulation is 550kHz to 1610kHz
What is the range of modulation index in am?
The range of modulation index in amplitude modulation (AM) is typically between 0 and 1. A modulation index of 0 indicates no modulation, while a modulation index of 1 represents full modulation where the carrier signal amplitude varies from zero to peak value.
Why modulation is necessary?
modulation is necessary for transmitting low frequency signal to long range with desired qualitative information
Frequency modulation range in India?
The frequency range of FM signal is 88hz to 108hz.
Why do you not use frequency modulation in long range transmission?
Frequency modulation is not used for long distance transmission because it has the problem of limited band width.
What is the main use of frequency modulation?
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.
What are the contrast of amplitude modulation to frequency modulation?
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.
What is the modulating frequency of amplitude modulation?
the frequency range of an am wave is 20herz to 20kilo herz
What does AM and FM stand for in radios?
AM - Amplitude Modulation FM - Frequency Modulation
How transmitted power is related to modulation index in am?
In amplitude modulation (AM), the modulation index (m) represents the ratio of the peak amplitude of the modulating signal to the peak amplitude of the carrier signal. The transmitted power in an AM signal increases with the modulation index, as higher modulation indices lead to greater variations in the carrier's amplitude. Specifically, the total transmitted power can be expressed as a function of the carrier power and the modulation index, with more power being allocated to sidebands as m increases. However, beyond a certain point, further increasing the modulation index can lead to distortion, as the signal may exceed the linear range of the amplifier.
