What is the advantage of a reflex klystron over a two-cavity klystron?
What is probably the primary advantage of the reflex klystron over the two-cavity klystron is the mechanism used to tune the device. The two-cavity klystron has mechanical tuning, but the reflex klystron is tuned electrically. And it doesn't take an electrical engineering degree for an investigator to figure out that electrical controls can be manipulated a whole bunch faster than a mechanical device.
Why phase modulation is used?
Actually phase modulation was used for the color signal in all analog TV systems.Phase modulation, with some signal preprocessing, was used to indirectly get frequency modulation in many FM transmitters.Certain modems use phase amplitude modulation.etc.
Explain in brief reflex klystron oscillator?
The Reflex Klystron:Another tube based on velocity modulation, and used to generate microwave energy, is the REFLEX KLYSTRON. The reflex klystron contains a REFLECTOR PLATE, referred to as the REPELLER, instead of the output cavity used in other types of klystrons. The electron beam is modulated as it was in the other types of klystrons by passing it through an oscillating resonant cavity, but here the similarity ends. The feedback required to maintain oscillations within the cavity is obtained by reversing the beam and sending it back through the cavity. The electrons in the beam are velocity-modulated before the beam passes through the cavity the second time and will give up the energy required to maintain oscillations. The electron beam is turned around by a negatively charged electrode that repels the beam. This negative element is the repeller mentioned earlier. This type of klystron oscillator is called a reflex klystron because of the reflex action of the electron beam. Check out the link below for more information.
What is ppm modulation?
pulse position modulation, used in many RC model aircraft controls.
In order to send more than one bit at a time during a single phase on a carrier modulation is used?
amplitude modulation is used

What does Base stand for in 100BaseT?
"Base band", meaning that no modulation is used."Base band", meaning that no modulation is used."Base band", meaning that no modulation is used."Base band", meaning that no modulation is used.
Where is delta modulation used?
Adaptive delta modulation is used in audio communication systems to avoid the two drawback of delta modulation.
What modulation is used in telegraphy system?
pulse code modulation method used a telephony.
Where is adaptive delta modulation used?

Why in titration of kmno4 no indicator is used?
Because KMnO4 is an internal indicator.. No need to have any indicator.. it has distinctly different colour when it is reduced
What is use of time delay in adaptive delta modulation?
It is used to delay the modulation
When does modulation take place?
If you speak loudly then softly you have used modulation of your voice
What type of modulation is used to carry the picture portion of a television signal?
Amplitude Modulation (AM) is used for the picture portion of a television transmission while Frequency Modulation (FM) is used for the audio portion.
What type of modulation is used in ADSL2?
For see the answer you want sign in but for write the answer you don't need any things.
