How can you make an electronic device that will buzz only if you separate it from the base unit to a distance after 3 meters probably work using frequency?
To create a device such as this one would chose a freguency is of a clear band width (avoid the upper frequency FM range) and mke the transmitter sufficiently weak that the signal would practically fade out in 3 meters. It is also possible to check the signal strength on the receiving circuit though this is prbably more sophisticated then need be as if you sufficiently under power, via gues nd check you should obtain the desired range.

What is the definition of genetic distance?
The "distance" or similarity between the allelic frequency of two separate populations. *Usually the two populations are separated over a significant geographic distance.
Why does every radio station have a different carrier frequency?
That's not exactly true. Any frequency you choose has several radio stations on it,but just not in the same city.Frequency is what your radio uses to separate the individual stations. If two stationsin the same city transmitted on the same frequency, your radio couldn't separate them.When you tuned to that frequency, you'd hear both of them at the same time, and youcouldn't understand either one.Listen to the 27 MHz 'Citizen's Band' some time.
What are the advantages of frequency shift keying?
In FSK the output frequency is dependent on the input bit stream. Here 2 (for Binary FSK) different carrier frequencies are used and they are switched according to input bit stream. When input is at logic1 output is freq. f1 and when input at logic0 output is freq. f2, where f1 and f2 are different.
What is the double conversion receiver?
A type of superheterodyne radio using two separate mixers, each producing its own intermediate frequency. The block diagram of such a receiver is like this: RF -> M1 -> IF1 -> M2 -> IF2 -> D -> AF
What is used as a dielectric in waveguide?
In waveguides, dielectric materials are used to separate conductive elements and influence the propagation of electromagnetic waves. Common dielectric materials include air, plastics, ceramics, and glass, depending on the frequency range and application. These dielectrics help maintain the waveguide's operational efficiency by reducing signal loss and controlling the wave's mode structure. The choice of dielectric affects the waveguide's characteristics, such as its cutoff frequency and bandwidth.

What is frequency domain modulation?
Do you mean FDM or Frequency Division Multiplexing? If so, FDM is the division of a high frequency carrier into separate non-overlaping bands to be modulated by separate inputs. It's the modulation of several low frequency channels onto a high frequency carrier. Voice channels are low bandwidth inputs relative to the broadband carrier used to broadcast them.
Does a 1998 EL Falcon have an electronic key?
it should have a remote which is separate from the key.
What is bi-wiring of speakers?
This is where the low-frequency driver, or woofer, is wired to a separate amplifier than the high-frequency driver or drivers. Also called bi-amping.
Is it true that a sound with a higher frequency is louder than one with a lower frequency?
No, frequency and loudness are two separate properties of sound. Frequency refers to how many cycles of a wave occur in a second, while loudness refers to the magnitude or intensity of a sound. A sound with a higher intensity is perceived as louder, regardless of its frequency.
After going with someone for 10 years will you ever get married?
Probably not. Something will probably separate you.
Will Electronic Rodent Repellers harm ferrets?
Oh, my friend, it's important to care for all creatures, great and small. Electronic rodent repellers emit high-frequency sounds that can disturb sensitive animals like ferrets. It's best to keep your furry friends in a separate area if you're using these devices, to ensure they stay safe and happy in their cozy little home.
How do you separate tea from water?
Probably by evaporation and then condensation
If a wave has a low frequency does it have a short wavelength?
The product of (frequency) x (wavelength) is always the same number ... the speedof the wave. So the lower frequencies must have longer wavelengths.

Why should we separate the core losses?
separation of core losses are necessary to determine core losses at diffrent frequency.........
Do orthodox sleep in separate beds?
Generally no, but there are probably a minority of them that do.
