What mode is less attenuation in circular waveguide?
TE10
What is the difference between attenuation and insertion loss?
In CATV system, insertion loss define as loss in directional coupler or TAP connector. typically 1 dBuv, while attenuation is generally describe as loss in transmission (splitter).
Why are waveguides used in high frequency?
I size of the object is comparable to wavelength, it will cause error. In high frequency wavelength is very low. So small-small objects will also cause interference, thereby increasing attenuation. Waveguides are hollow metals. Thus wave does not go out and stay inside. Metals does not cause any attenuation. Propagation of EM wave in waveguide is similar to light in optical fiber.
What is the sodium hypochlorite dielectric constant?
dielectric constant for sodium Hypochlorite
How do you calculate the time constant for a simple series RL circuit?
The time constant of an RL series circuit is calculated using the formular: time constant=L/R
Difference between attenuation constant and phase constant?
nothing
An increase in temperature will the attenuation of a cable?
Basically we should also keep in mind knowledge about voltage and current. If we keep voltage constant then by increase in temperature also increase the attenuation, if we keep current constant then attenuation drops by increasing temperature.
How heavy is 1lb of lead in 600ft of seawater?
One Pound, The Earth's gravity well is a constant.
Drawbacks of constant k type filters?
Drawback of the constant K type filter is that at the cut of frequency , its attenuation is a steady curve .. quick response is lacking in it an ideal filter should have a sharp response curve.
Does attenuation happen when EM wave travels in space?
There is no attenuation due to absorption, but attenuation will occur due to divergence (spreading out) of the wave.
What is a good value for dB attenuation?
6 dB is a "good" attenuation.
How do you reduce attenuation effects?
We can reduce attenuation effects bt using repeaters
What is breast attenuation as in nuclear stress test?
breast attenuation correction meethods
Where can you find information about attenuation?
Attenuation means the reduction of signal strength during transmission. If one is looking for information about attenuation, it can be found on the Wikipedia website.
Non-desructive attenuation for attenuation measurement in optical fiber?
Because race car.
Difference between m-derived filters and constant k-filters?
in m derived impedance matching is possible but not in case of constant k filters. compared to constant k filter m derived filter has a sharp cutoff frequency. in k type the attenuation is not complete in the stop band.where as in the m derived just beyond the attenuation rises to max just after the cut off frequency. in m derived a capacitor and a inductor are taken in series at the output.
Why are repeaters used between computers?
Because - even in fibre-optic cable, distance brings attenuation of the signal. Repeaters boost the data stream to provide a constant signal level.
