frequency
A change in frequency of the motor will cause a change in the speed of the AC conveyor motor. This frequency change is brought about by a device called a Variable Frequency Drive. It is used to vary the frequency of the motor from 0 to 100%. I have no idea what the second answer is talking about. ANSWER: considering that no mention of type of motor is involved the frequency change theory is quite invalid since 50 or 60 Hz AC line runs clocks from banks to wake up calls and while it is true that the frequency is not accurate from second to second it is however very accurate from minutes to minutes.
Resonant means something vibrates at a given frequency. Usually if you can get an object to resonate at its resonant frequency - it will disintegrate ! For example - if you tap a wine-glass, it 'rings' - that's it's resonant frequency. Now - take a speaker and play the exact frequency through it, while holding it close to the glass - after a few seconds it will shatter because the glass vibrates too fast.
How do you convert cellphone gsm frequency to another gsm frequency?"
The signals frequency directly.
slow frequency hopping (SFH) technology. The difference between slow frequency hopping and fast frequency hopping is that the frequency of latter changes faster than frequency modulation
Slow frequency-hopping spread spectrum (FHSS) systems hop between frequencies at a lower rate, typically around 1-5 hops per second, while fast FHSS systems hop at a higher rate, often over 20 hops per second. The main difference lies in the speed of frequency hopping, with fast FHSS providing increased resistance to interference and higher data transmission rates compared to slow FHSS systems.
Your question is pretty open.. depends on the frequency, it can be slow or it could be fast
TSK
Multi wave propagation varies the signal strength which causes fading dips. This is known as Rayleigh fading which is frequency dependent. Frequency Hopping changes the frequency with time to eliminate frequency dependent Rayleigh fading. Frequency Hopping reduces the effects of interferences and gives a great support to cater the capacity upgrading as well.
Fast frequency hopping spread spectrum (FHSS) systems switch between frequencies rapidly, usually several times per second, to avoid interference and jamming. Slow FHSS systems switch between frequencies less frequently, providing a more predictable and stable connection but potentially making them more vulnerable to interference.
The speed at which an object vibrates determines its frequency, which is measured in hertz (Hz). Objects that vibrate faster have a higher frequency, while objects that vibrate slower have a lower frequency.

FHSS(Frequency Hopping Spread Spectrum)
SINCGARS uses frequency hopping spread spectrum (FHSS) technology to reduce the threat of jamming. FHSS allows the radio to hop between different frequencies in a predetermined pattern, making it harder for adversaries to jam the signal. This technology also helps minimize the need for direction-finding equipment by providing secure and reliable communication.
The speed at which an object is vibrating is called its frequency. The frequency is typically measured in hertz (Hz) and represents the number of vibrations or oscillations per second.
not a fast but slow
