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.

The Hertz is a unit of frequency(Hz). 1 Hertz is equal 1 cycle per second. 2 Hertz is equal 2 cycles per second. ... mega means 10^6 mhz means megahertz what is 10^6 Hertz = 1000000 Hz 72.790 mhz is equal a 72.790 * 1000000 Hz. It is a high frequency. Currently the computer processors are measured in gigahertz(GHz) = 10^9 =1000000000.
Where is message left after deleting in mobile sets?
Do you know where you have deleted files on you phone,You go in there then it should have the message you deleted and you can go in and get the file,but the phone will not allow you to read it only if you can do the math to get it and you can only see the message you can't put it out of deleted files(it is possible if you go options save then transfer)
Only on sertin phones Samsungs+nokias+LGWhat is the meaning of sink source in PLC?
Sink - A wiring arrangement in which the I/O device provides current to the I/O module Source - A wiring arrangement in which the I/O module provides current to the I/O device
What are the Differences between horn antenna and waveguide?
- waveguide is a metal pipe that contains and guides microwaves from place to place in a microwave system (e.g. oscillators, amplifiers, mixers, modulators, filters, antennas)
- horn antenna has a waveguide connected at its focus, in transmit mode the waveguide feeds the horn which then emits a microwave beam, in receive mode the horn collects a microwave beam and concentrates it int the waveguide
What is 'smoothing filter' in digital image processing?
smoothing is a noise reduction technique that derives its name from the fact that it employs a simple, fast filtering algorithm that sacrifices noise suppression power in order to preserve the high spatial frequency detail (e.g. sharp edges) in an image. It is explicitly designed to remove noise spikes --- i.e. isolated pixels of exceptionally low or high pixel intensity (e.g. salt and pepper noise) and is, therefore, less effective at removing additive noise (e.g.Gaussian noise) from an image. biometrics@hotmail.com
What can printed circuit boards be used for?
PCB or printed circuit board are copper clad that are chemically etched to establish connections with parts installed on it making it a working circuit
Today, just about every electronic appliance in your home contains a printed circuit board of some type: computers, printers, televisions, stereos, musical instrument amplifiers and synthesizers, digital clocks, microwave ovens, telephone answering machines and even cell phones. The "motherboard" in a computer is the main printed circuit board that is the heart of a computer. Other circuit boards inside a computer performs functions such as RAM (random access memory), power supplies, modems and video "cards."
How can an op amp comparator circuit be used for converting sine to square wave?
The wording are confusing an op-amp is an op-amp a comparator is another animal. an op-amp can be used as square wave generator by overdriving it but the results are not desirable. However a comparator will be a switch on-off at the set level.
Will an open switch record a resistance of zero ohms?
no...... ideal open switch should have a resistance of infinity... the question should be a closed switch http://wiki.answers.com/Q/Will_an_open_switch_record_a_resistance_of_zero_ohms" but this is also false because any good conductor will have a small resistance the connecting wire resistance is exhibitted across the terminals of the switch
One microfarad equals how many farads?
1 microfarad = 1uF = 10-6 F = 0.000001 F
mili = 10-3
micro = 10-6
nano = 10-9
pico = 10-12
In any parallel circuit within a combination circuit the greater current will flow through the?
lowest resistance
Cut off cet ranking for rvce collage of engg?
I my self ama a studnt of RVCE. In order to get some idea follow dis link below

Watts are a unit of power and Volts are a unit of electric potential, so they cannot be directly compared. However, Watts and Volts can be related by
Watts = Volts * Amperes
or
Watts = (Volts^2) / Ohms
where Amperes are a unit of current and Ohms are a unit of resistance. So, for example, if a lightbulb draws .333 Amps of current at 120 Volts, it is a 40 Watt bulb. (.333 A * 120 V = 40 W)
tri state means three states of operation. usually it is used on data buss whereby data is transferred to peripheral devices called I/O the transfer is 0 or 1 on a try state device if not zero or one the buss goes to open state which makes a tri state device.
How do you know which way a diode will let current flow?
Most diodes have a band (or marking), at one end. The band end is considered the positive end. You can also consider the "band" as a symbol of a gate or blockage. Power flowing from the non-band end to the band end will flow, but power flowing from the band end backwards will not. (That's my method that works for me).
What are the 3 kinds of variable resistors?
by getting hoy and having a native harass a young pool stick with a slab of meat
Why be use the -48 volt for bts?
48 is volt scale and negative voltage is used for safety of media, to prevent attanuation and noise.
What do you mean by trigger in a flip-flop?
A flip flop is a quiescent component meaning it can have one of two states A trigger or signal is required to force the flip flop to change state
Do cell phones use radio waves or microwaves?
Microwaves are radio waves.
Technically, "microwave" is the term used to designate radio communication on
frequencies above 3 GHz. Cellular and mobile data service doesn't operate in
that frequency range. But microwave systems operating in bands between
5.8 GHz and 80 GHz are used to link the individual cellular and mobile data sites
to each other, and to the mobile switching centers.
Why meter bridge can't be used to measure low resistance and high resistance?
used to measure low Resistance since it must reach a null.
Current will flow as long as there is a difference of potential (a voltage) and a path for current to flow. So no power-control device is required for current flow but yes it will flow with a power control decive.
