What property of modulating frequency is varied for frequency deviation?

∙ 16y ago
FM is the carrier property when terms like `frequency deviation' are used.
Unlike AM, which has a single frequency, and the frequency is modulated by increasing the amplitude of the frequency, with FM, it's the frequency itself that is changed, either by making the frequency a bit higher or lower from the actual stated frequency.
For instance, a FM radio station located at 100.00 on the dial will have the frequency deviate by plus or minus 75 kilohertz (+100.075 HZ or - 99.925 HZ.) or more commonly referred to as a bandwidth of 150 KHZ. for 100% modulation.

What is the relation between carrier frequency and modulating signal?
If the modulating system is AM (Amplitude Modulation) then the amplitude of the carrier wave changes with the amplitude of the modulation. On a specrum analyser that shows up as frequency sidebands. If the frequency of the carrier waves depends on the amplitude of the modulating signal that is called FM (frequency modulation). On a spectrum analyser that shows up as sidebands also.
What is capacitor transducer?
A: Some material have the property of a capacitor and this property can be varied by outside forces making it a transducer
Why is a limiter used in FM?
limiter mainly used to limit the amplitude of FM waveform.because of, in FM the frequency only varied but amplitude also varied due to noise . to cancel the amplitude variation limiter mainly used
What is the difference between microwave and an AM signal?
The primary difference is that the microwave signal is of a much higher frequency than an AM signal, if that AM signal is speaking to AM broadcast radio. In general, AM, or amplitude modulation, is not generally used as a modulation technique on microwave frequencies because there are other ways to put a signal on a microwave carrier that allow more information to be transmitted. AM is "low frequency" RF, while FM is a bit higher on the radio frequency spectrum, and microwaves are further on up.
Can you replace a 2-30 trimmer capacitor with a fixed value capacitor?
Yes you can. But the variable one is used so that you can very the frequency and it cant be varied anymore if you use a fixed capacitor.
What is Modulation index formula in Frequency modulation?
The modulation index formula in frequency modulation (FM) is given by the equation: β = Δf / fm, where β is the modulation index, Δf is the peak frequency deviation, and fm is the modulating frequency. Modulation index indicates how much the carrier frequency is being varied by the modulating signal in FM.

What are the parameters of high frequency carrier that may be varied by a lower frequency intelligence?
Following are the 3 parameter by which high Frequency carrier can be varied by low frequency intelligence signal 1) Amplitude 2) Phase 3) Frequency
Why the output of the envelope detector changed frequency when the audio frequency was varied?
answer for me please
Comparison of amplitude modulation and frequency modulation?
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.
What type of modulation is pulse position modulation and why?
It is a type of Pulse modulation as in PPM the position of pulse of carrier pulse train is varied in accordance with the modulating signal.
What is the 'carrier' in the EM spectrum?
The carrier could be light, radio waves, almost any of the wave energies in this spectrum that are not hazardous to life. When used to convey information they are called carriers because one or more characteristics of the wave are varied to encode the information. One of the simplest forms of encoding or modulating a carrier is amplitude modulation which is used to make radio frequencies carry sound. The amplitude of the radio frequency signal is varied in step with the sound.
What is capacitor transducer?
A: Some material have the property of a capacitor and this property can be varied by outside forces making it a transducer
What is meant by am in radio?
Amplitude Modulation- AM standard Broadcast band. AM is an abbreviation for amplitude modulation,a form of radio transmission in which the carrier radio wave's amplitude is varied according to the strength of the modulating signal(sense).
What is a sweep test?
A sweep test is a method that determines the frequency response of a cable by its generation of RF voltage. This frequency should be varied at a rapid constant rate.
How can the frequency of incident radiation be varied?
The frequency of incident radiation can be varied by changing the energy level of the source emitting the radiation. For example, in the case of electromagnetic radiation like light, increasing the energy of the source (such as a higher voltage in the case of X-rays) will result in higher frequency radiation. Similarly, for radioactive decay processes, the frequency of emitted radiation can be controlled by manipulating the radioactive material's properties.
What is A testing device for radio sets in which the frequency is varied periodically and automatically over a predetermined range?
