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
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.
Why modulation is necessary?
modulation is necessary for transmitting low frequency signal to long range with desired qualitative information
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 is the modulating frequency of amplitude modulation?
the frequency range of an am wave is 20herz to 20kilo herz
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 modulation of frequency?
It is a device or electronic circuit that changes the frequency of an oscillator according to the amplitude of modulating signal. For instance, if the modulation is linear, the modulator changes the frequency proportional to the amplitude of the modulating voltage.
How phase lock loop is used as a universal detector for Amplitude Modulation?
A phase-locked loop (PLL) can be used as a universal detector for Amplitude Modulation (AM) by utilizing its ability to track the phase and frequency of the incoming modulated signal. The PLL locks onto the carrier frequency of the AM signal, allowing it to demodulate the envelope variations caused by the modulation. By comparing the output of the PLL with the original carrier frequency, the modulation information can be extracted as the difference between the two signals. This makes the PLL an effective detector for demodulating AM signals across a wide range of frequencies and modulation depths.
What is the subwoofer frequency range of the audio system you are considering purchasing?
The subwoofer frequency range of the audio system I am considering purchasing is 20Hz to 200Hz.
What is the need of digital modulation scheme?
The aim of digital modulation is to transfer a digital bit stream over an analog bandpass channel, for example over the public switched telephone network (where a filter limits the frequency range to between 300 and 3400 Hz) or a limited radio frequency band.
Which require higher bandwidth FM or AM and why?
Frequency Modulation (FM) requires higher bandwidth than Amplitude Modulation (AM) due to the nature of how each modulation method encodes information. FM varies the frequency of the carrier wave to transmit information, which results in a wider range of frequencies being occupied. In contrast, AM varies the amplitude of the carrier wave, which occupies a narrower bandwidth. As a result, FM typically requires about 10 times more bandwidth than AM to accommodate the greater frequency deviations used in the modulation process.
