The process whereby a time varn in vel is impressed upon the beam of el is called vel modulation.
The Magnetron tube is quite different from the Klystron tube. The Magnetron tube is can only function as an oscillator only.
in twt electrons are constant with rf field for long time&in klystron for short time. in klystron electron constant with r.f field with long time& in twtare shot time.
klystron can act as both an amplifier and oscillator whereas a reflex klystron can act as only an oscillator. klystron needs a buncher cavity(sometimes multiple bunchers) and a catcher cavity whereas a reflex klystron needs only one cavity. klystron bunches electrons in forward direction, whereas the other bunches in the reverse direction using a reflector plate. klystron needs i/p signal (accelerating or deccelerating potential) whereas the other dont.
Velocity is speed with direction
The technical difference is that speed has no direction but velocity has one.
There is no difference.
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
The difference between pulse code modulation and delta modulation is that pulse code modulation is a method of encoding audio information digitally while delta modulation is a method that converts analog to digital signal.

The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
klystron can act as both an amplifier and oscillator whereas a reflex klystron can act as only an oscillator. klystron needs a buncher cavity(sometimes multiple bunchers) and a catcher cavity whereas a reflex klystron needs only one cavity. klystron bunches electrons in forward direction, whereas the other bunches in the reverse direction using a reflector plate. klystron needs i/p signal (accelerating or deccelerating potential) whereas the other dont.

The technical difference is that speed has no direction but velocity has one.
muzzle velocity is the velocity of bullet and recoil velocity is the velocity of gun.
Acceleration is the rate of change of velocity.
The Difference of two is only first digital has a transmission and second digital has modulation.....thats all....i think that's too clear ha...
