What is an electrosurgical generator?
An electrosurgical generator is a piece of medical equipment. The generator takes mains AC current and turns it into radio frequency (>100Khz) AC current. This current can then be used to cause a tissue effect in a patient (i.e. cutting, coagulation, fulguration).
How do you calculate the change of frequency of a quartz crystal by applying pressure on the crystal?
you compress and release the pressure on the quartz buy changing the electrical polarity (force) the speed of sound in the crystal determines the frequency so for about 1000 ft / second if the quartz is about .01' 1/8" thick you get about 100khz applying more pressure increases the amplitude making the frequency lower too much power (force, pressure) you will break the crystalo
Can human hear sound above 100kHz?
Not usually, 15-22 kHz is the upper limit in normal hearing.
What is difference between pulse width modulation and pulse position modulation?
Frequency modulation, as the name suggests, modulates the carrier by changing the frequency of the signal emitted. Pulse width modulation, changes the on-time of a square wave, but leaves the frequency of the carrier wave unchanged. So, in frequency modulation, the frequency will vary between, say, 80kHz and 120kHz with a constant power level, but in pulse width modulation, the frequency will stay at 100kHz, but the on-time (the length of each pulse) will vary, hence the power level will vary accordingly.
Which two frequencies of light are invisible to the human eye?
100kHz and 101kHzA2. I think the questioner wants Ultra violet and Infra red.
What is line trap used for?
A line trap is essentially a band rejection filter. It is tuned to a specific frequency and blocks that frequency. In the power transmission system, these are often used to limit the transmission of communication signals to specific lines; say a 100kHz signal is injected on either end of one line for the sake of communicating between subs; the wave trap is used to stop this signal from propogating to other lines and other subs (where it could mess with those communications).
What is the frequency fo radio waves in hertz?
From around 100kHz to around 500MHz. Below that, antennae need to be rather long to be efficient, above that the transmission range gets a bit short. But people have used much lower, and much higher frequencies, 40Hz - 20Gz and higher. The very high frequencies are often called microwave links.
What is the best frequency for audio eg. 44 100kHz?
1) Best frequency for what? The human hearing range is 20 Hz - 20 000 Hz, so in that sense, no. The ear is most sensitive to ~3khz, see Fletcher-Munson curve. 2) But for editing and recording, I would say 24 bit 96 kHz, because they handle noise floor and time stretching quite well, but for exporting to CD, 16 bit 44.1 kHz 3) it's 44 100 Hz, not kHz. that is same as 44 100 000 Hz, which is a big difference.
You just got an HD TV and the sound is tinny or a bit off you try to change it but the settings are all like this - 100KHz and 1.5MHz what do you need to change to make it sound less tinny?
the peanut butter takes effect on the tv and turns it into scotland......not quite
Where is the microwave radiation located on the electromagnetic spectrum in relation to other kinds of radiation?
It's really quite simple actually... They lie right between the electro-convulsive synapse, and the photo-ludacritic cleft. It's a very delicate balance, even the slightest amount of refractive shift micteration and the whole spectratic waveform becomes unrecognizable to even the swiftest of retinal sphincters.
Why in gsm we are taking 200kHz as bandwidth why we cant take 100kHz or some thing less than 200kHz so that we can increase the ARFCNs.?
because we can use 99% of 270.5 kbps which is normally used for air interface in gsm, to get a minimum bit error rate of 1% and 8/1 db sn ratio.
Can humans hear all sounds?
You would think humans could hear all sounds but some can be below or above the frequancy of the humans ears:) +++ Very much so. For a healthy, fully function human ear, the lowest frequency is 2oHz, the maximum 20kHz, but age and long-term exposure to loud sounds will reduce the upper limit for an individual. Frequencies <20Hz are described as "infrasound"; made by some animals for communication. Frequencies >20kHz: ultrasound. Echo-locating bats call at around from 80kHz to above 100kHz when hunting (and some do so at very intensities, too, though at very low power as they are only little animals). Medical ultrasound frequencies exceed >1MHz.
