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.
