Electronics Engineering
Electronics Engineering is a branch of engineering that deals with practical applications of electronic components, devices, systems, or equipment. Electronics are devices that operate on low voltage sources, as in electron tubes, transistors, integrated circuits, and printed circuit boards and use electricity as part of its driving force.

What is the uplink frequency of a satellite?
Uplinking refers to the transmission of a signal via a satellite from one terrestrial location to another location and then ultimately the signal can be distributed to the end users.
What is the role of uplinking in the entertainment sector?
In broadcasting, broadcasters use uplinking to beam their programmes to their viewers across countries. Typically, they hire the services of a transponder or a transponder itself that will be used to beam the broadcaster's programmes to the receiving country.
What is the Indian policy on uplinking?
Till some time ago, there were restrictions on uplinking from India. In July 2000, the government liberalised uplinking and allowed Indian companies to set up their own teleports to uplink directly from India. Television channels were also allowed uplinking facilities. The foreign equity holding of such companies should not exceed 49%.
The frequency of uplinking varies from user to user according to band assigned. Many upling frequency is 4mhz in c band and 10 mhz in ku band
Generally uplinking and downlinking frequencies are kept different in order to minimise interference and distortion.

500 volts rms is equivalent to what dc voltage level?
it will be no DC not unless diodes and capacitors are applied. rephrase the question
A DVOM is set to the 400 V range If a 12 volt source is measured what will be the meter display?
12 volt
What kind of current used in train?
Trains use DC currents!
It's predominantly AC now but more dc in the early days. Both still in use. See DC and AC section below article-
What is the difference between guassian laplacian and gabor pyramids?
It is simple - An input image is subsampled in the same way - the only difference is that a smoothing kernel one might use, which is {gaussian, laplacian, or gabor kernel}. Hope this helps!
hii i am jaykishan from rajkot
magic tee used as power combiner and power divider
it used as isolator too
How do you join a cut rg59 cable?
If it's indoors you would go to the local electronics store (i.e. radio-shack) And pick up two RG-59 cable ends and a barrel connector (sometimes called a coupling) Just put an end on each piece of cable, they will come with instructions, and then screw them together with the barrel.
You can also use wire nuts but it may cut down on the quality of the signal. Just strip off some of the outer sheath, and then a bit of the inner sheath. Twist the center copper wires together, and then twist the outer shield (silver mesh) together making sure that the copper wires don't touch the silver. If they do touch it won't do any harm, but it won't work.
What is the effect of the reverse bias on the width of the PN junction?
The holes and electrons move away from the junction and attracted towards the terminals as the positive polarity is connected to the n-side and negative polarity to p-side.
What is slope over distortion?
i believe you mean that the question is to do with the gradient of a line
the gradient of a line is the change in height divided by the change in distance
which is the same as slope divided by distortion
if a man goes up a hill and his height cahnges by 1 metres vertically and he walks horizontally 10 metres then the slope is 1 metre and the distortion is 10 metres.
Gradiend is 1 -10th or 10%.....
What is the purpose of having an lc circuit in an amplifier?
Because , ic can provide :-
1. very high gain
2. compact & less bulky circuit
Ripple.
Explain Working principle of electrodynamometer type of instrument?
The working principle of a basic electrodynamometer instrument is same as the PMMC instrument. The only difference in this case is that the permanent magnet is replaced with two fixed coils connected in series. The moving coil is also connected in series with the fixed coils. The two fixed coils are connected to electromagnets in such a manner that they form poles of opposite polarity. As the moving coil carries current through it and is being placed in the field of fixed coils, it experience a force due to which the moving coil rotates. The direction of this force is independent of the supply voltage as the current flowing through fixed coils and moving coil is one and the same. If the direction of current changes in the moving coil, then the field direction also changes, thus making the torque unidirectional.
Why is midpoint biasing desirable?
Midpoint biasing is desirable because it enhances the accuracy and reliability of data analysis by reducing systematic errors in measurements. By centering values around a midpoint, it minimizes the influence of outliers and extreme values, leading to more representative results. This approach also helps in achieving a more balanced perspective when interpreting data, ultimately improving decision-making processes.
Is it true you got a power that you did not know?
If you are referring to an old Pokemon game where you can find a TM called ancient power or something like that, it is a move that depends on the abilities and type of the creature that you choose to teach it.
What are the five reasons why engineers study economics and management?
they innovate new things. by having a knowledge of economics and management they can forcast or can predict the utility,advantages,disadvantages of the product. also get to know the scope of the product and it's contribution in growth.
What Number Comes After Quadrillions?
The number one quadrillion has 15 zeroes in the short scale and 24 zeroes in the long scale.
Adding three zeroes in the short scale gives one quintillion. In the short scale, this is 1 followed by 18 zeroes (1,000,000,000,000,000,000), while in the long scale, this is 1 followed by 30 zeroes (1,000,000,000,000,000,000,000,000,000,000).
What is situational attribution?
when we attribute someone's behavior to being a product of their ENVIRONMENT
