What are the microwave tubes is based on the principal of velocity modulation?
the microwave tubes that undergoes velocity modulation are klystron tubes ie, two cavity klystron.....
Difference between velocity and current modulation in klystron?
The process whereby a time varn in vel is impressed upon the beam of el is called vel modulation.
What is velocity modulation in klystron?
As we know in klystron tube drift space is assumed to be free of any electric field. Therefore, the high velocity electron emerging in the later period are able to overtake the low velocity electrons leaving the buncher grids. As a result of these actions, the electrons gradually bunch together as they travel down the drift space. This mechanism of variation in electron velocity in the drift space is known as velocity modulation.
Who invented velocity?
the person who discovered velocity was newton. so you should look up newtons theory on velocity.
What is Modulation index formula in Frequency modulation?
mf=(K*Am)/fm where K: is a proprtionality coefficient Am: is amplitude of the message fm=frequency of modulation
How velocity modulation and density modulation related to each other?
due to velocity modulation density modulation occurs in TWT
How velocity modulation is different from normal modulation?
As we know normal modulation is superimposing the wave with another carrier signal but the concept of velocity modulation is totally different, as The modulation in velocity of a beam of electrons or ions caused by passing the beam through a high-frequency electric field, as in a cavity resonator there is no concept of superimposition.

What does am frequency stand for?
AM stands for Amplitude Modulation. In theory, amplitude modulation could be applied to a radio signal on any frequency but the AM band on most domestic radios stretches from 530 to 1700KHz.
