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.

It's an op amp (operational amplifier) with a linear response, meaning that double the input means double the output.
-- So long as the AM modulation index doesn't exceed 100%, only one set of
sidebands exists, and the spectral width of an AM signal is double the highest
modulating frequency ... 10 KHz in this case.
-- Dealing strictly with the arithmetic ...
6 MHz/10 KHz = 600 AM channels in the equivalent of one analog TV channel.
-- But 6 MHz of AM spectrum could never be used that way, because ordinary
consumer-grade AM radios can't deliver a listenable program in the presence of
another signal of equal nominal level on the adjacent channel. With all of these
AM stations all in the same metro area, you'd need to figure at least one guard
channel between adjacent AM stations ... reducing the capacity of your 6 MHz
to no more than 300 stations, because of typical receiver quality (or lack thereof).
-- Also, of course, notice that with 300 AM stations in one market, none of them
could sell any appreciable amount of commercial time, because none of them would
have any appreciable audience, and half of them would die in the first month.
-- Finally, when you start thinking about commercial spectrum utilization, it's
important to be aware that whereas this little exercise speaks in terms of the
equivalent of one whole analog TV channel dedicated to AM broadcasting, the
entire real-world AM broadcast band is barely 1/6th of that much ...
530 KHz - 1700 KHz = 1.17 MHz !
so the input of a elevator is the people and the output of an elevator is the people getting out of the elevator
What is the formula for real power?
volts times amps equal watts, or 550 lbs per sec equals 1 horse power.
List Examples of electronic monitoring and surveillance equipment?
ankle monitors, home monitoring systems, and GPS to name a few.
The different types of FLAGS register?
There are a huge number of different FLAG registers. The most common are zero flag (Z), carry flag (C), sign flag/ negative flag (S/N), and overflow flag (V/O/W). Each flag contains different information about the state of the processor.
Why microprocessor opcode fetch will 6 t states and 4 t states?
different microprocessors take different number of states. without knowing processor its not possible to comment.
The special instrument that is placed in the heart and used as a impulse generator is called pacemaker. The pacemaker helps the heart to make it fuction normally....
Does the audio system in a 1996 Suburban have a separate amplifier?
Yes. There's a factory amp under the driver's seat (bucket seats option).
What is the element used to make semi-conductors?
ice cream lollies and pie. this is a very healthy combination of foods. this will defiantly help you loose weight.
Is there a way to convert an FM antenna input plug on a home stereo into a 3.5mm jack?
there are adaptors available to do this
What is detection antenna housing called?
The housing used for a detection antenna is called a radome. This type of housing is made from transparent material, which is often found on the outer surface of an aircraft.
LMI
What is the advantages of using a MTI with a radar?
If we use only stationery target indication radar then we can't recognize targets are whether moving or stationary. next time previous will be indicated as new object appear at another place when we don't use MTI with radar.
Magnetising characteristics of DC shunt generator?
the magnetizing curve is the relation b/w air gap flux and the field winding current armature EMF. the resulting curve is called magnetizing characteristics or open circuit characteristics. at any speed by recognizing that the induced emf is directly proportional to the speed
The Output is stuck at either '0' or '1'?
O/P Stuck at - '1': One input combination is enough (All 1's). So that output should transition from '1' to '0'.
O/P Stuck at - '0': 7 combinations possible (000, 001, 010, 100, 101, 110). But only one is enough. Output should transition from '0' to '1'.
So 2 input vectors necessary to verify the three input NAND gate stuck fault.
cold soldering is when the soldring part is not well soldard or the soldring has being disjoint.
Which transister is used in emitter follower circuit?
A: Any transistor of either polarity can be used as an emitter follower, The purpose of an emitter follower is to provide current to the load since it cannot provide any voltage gain
In what type of appliance would you use a circuit with batteries in parallel?
Batteries in parallel is not recommended. Not unless they are equalized. the appliances can be one guess since the battery only see a load
Full load copper loss of a 100 KVA transformer is 800W Its copper loss at 75 percent load will be?
100 is to 800 as 75 is to X. Cross multiply, 100 x X and 800 x 75, 100X = 60000. To get rid of the 100 divide it into both sides of the equation. X = 600.
If the copper loss is linear, at 75 percent the copper loss will be 600 watts.
In India the alternating current ac change its direction time within one second?
I believe India runs on 50Hz power, so 100 times.
What is a tachogenerator in control system?
a device to measure rotation speed of a shaft as a proportional voltage
