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.
What is the Difference between klystron tube and twt?
Klystron tubes use velocity modulation of electron beams to amplify microwave signals, while traveling wave tubes (TWTs) use interaction of electron beam with a slow-wave structure for signal amplification. Klystrons have higher efficiency but limited bandwidth, while TWTs have lower efficiency but wider bandwidth. TWTs are commonly used in satellite communication and radar systems.
Difference between delta modulation and differential pulse code modulation?
Delta modulation is not a type of quality conversion and runs on digital-to-analog, analog-to-digital. Differential pulse code modulation has a higher quality of conversion and runs on a 1-bit data stream.
What is the difference between the two cavity klystron amplifier and reflex klystron?
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.
How to find the change in velocity in a given scenario?
To find the change in velocity in a given scenario, subtract the initial velocity from the final velocity. The change in velocity is the difference between the two velocities.

What is the difference between space vector modulation and pulse width modulation?
There is no difference.
What is the difference between frequency modulation and phase modulation?
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.
What is the difference between pulse code modulation and delta modulation?
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.
What is the difference between analog and digital modulation Does it depends on baseband signal?
The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
Difference between delta modulation and differential pulse code modulation?
Delta modulation is not a type of quality conversion and runs on digital-to-analog, analog-to-digital. Differential pulse code modulation has a higher quality of conversion and runs on a 1-bit data stream.
Difference between digital transmission and digital modulation?
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...
Compare pulse code modulation and delta modulation?
delta modulation refers to the procedure of encoding and thereby transmitting only the difference between consecutive samples instead of sending each of the samples themselves. This method is useful only when the vaiation in the amplitude of the signal is small, otherwise, it leads to a phenomenon called "slope overload".Pulse code modulation is the procedure where each of the levels of an analog signal is assigned a value closest ro a quantizer level used to quantize the signal...Another method of PCM that can be confused with Delta Modulation is the D(ifferential)PCM. Here, the difference between the signals is encoded based on its magnitude..
The distance between speed and velocity is that velocity includes?
Velocity includes direction. And it's the 'difference', not the 'distance'.

What is the difference between am raido and FM radio?
A: AM radio is an Amplitude Modulation transmission . Meaning it has fix frequency but it is modulated by the signal. FM Frequency Modulation the frequency is modulated by the signal
