What is the advantage of microwave frequency over low frequency?
larger bandwidth beter directivity lower power requirement less fading effect
What is the change in frequency of a sound due to motion of the source?
The change in frequency is caused by the Doppler Effect
How do you calculate the power output with a changing frequency?
Frequency has no effect on power output. Impedance, Voltage, and Current all affect Power (watts).Use the following formula(s) to calculate power:E^2/R R*I^2 E*IFor more information study Ohm's Law.AnswerThe power of an a.c. load is given by P = U I x (power factor). Power factor is the ratio between resistance and impedance. Impedance is the vector sum of resistance and reactance. And reactance is affected by frequency. So, yes, frequency does affect the power of a load. To calculate the power for different frequencies, just work through the factors listed in the preceding sentences.
What determines the frequency of an electromagnetic wave?
The frequency of the source that produced the wave.
What is the doopler effect?
The apperent frequency observed by a observor different from natural frequency when there is relative motion between source and observor
What is the advantage of microwave frequency over low frequency?
larger bandwidth beter directivity lower power requirement less fading effect
What is the formula to calculate EIRP?
EIRP= Power of transmitter(dbw) + Antenna Gain (dBi) - (Feeder Loss + Combiner Loss) Feeder Loss depends on operating frequency, type of feeder (coax, waveguide, ladder-line, etc.), and nominal frequency for which the feeder is designed.
Effect of high frequency sounds in birds?
effect of high frequency sounds
What effect does the amplifier have on the frequency of the signal?
No effect on frequency but increases it's amplitude.
What happens when a signal is sampled below its Nyquist frequency?
Introduces the aliasing effect which eventually would account for information loss...(aliased signals)
A sensorineural hearing loss is most often associated with loss of hearing sensitivity in which of the frequency ranges?
high frequency sounds
Frequency to power?
THERE ARE NO FREQUENCY TO POWER CONVERSION rephrase the question
What frequency corona loss is more?
frequency is directly propotional to corona loss... so higher the freq the corona also high..
Is controlling frequency and severity of loss events can reduce risks?
Yes, controlling frequency and severity of losses reduces overall loss.
Can controlling frequency and severity of loss events reduce risks?
Yes, controlling frequency and severity of losses reduces overall loss.
Which transistor is used for high speed power application?
In transistor the heat is created during transition stage means from cutoff to saturation and reverse, so if transistor used for high frequency application power loss can be minimized. The heat produced during switching is actually power loss.
Why uplink frequency is kept higher than downlink freqquency in satellite communication?
due to path loss : higher is the frequency higher is the patrh loss
