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.

How do you choose micro farad capacitor for dc voltage?
To choose a microfarad capacitor for DC voltage applications, first determine the required capacitance value based on the circuit's needs, such as filtering, decoupling, or timing. Next, assess the voltage rating, ensuring it exceeds the maximum DC voltage the capacitor will encounter, typically by at least 20-30% for safety. Additionally, consider the capacitor's temperature rating and ripple current capability to ensure reliable operation under your specific conditions. Finally, check for characteristics like equivalent series resistance (ESR) and longevity based on the application environment.
Double conversion transponder?
In a double conversion transponder , the signal received from the ground station is converted into IF , then the signal is filtered & amplified . Finally the IF signal is again upconverted to desired frequency and transmitted downwards.
How does consistency result from controlling redundancy?
consistency is when you have all the facts straight, when you say the same thing at all opportunities. The word has a positive connotation, suggesting that the story 'holds together', has no disagreeing facts. Redundancy means the same thing but has a negative connotation, suggesting that you say the same thing too many times, more times than is necessary to be consistent. Therefore if you control your redundancy (limit it in some way) you will achieve sufficient consistency without being boring.
What is difference between spld cpld?
SPLD - Simple Programmable Logic Device
Also known as:
- PAL (Programmable Array Logic, Vantis)
- GAL (Generic Array Logic, Lattice)
- PLA (Programmable Logic Array)
- PLD (Programmable Logic Device)
SPLDs are the smallest and consequently the least-expensive form of programmable logic. An SPLD is typically comprised of four to 22 macrocells and can typically replace a few 7400-series TTL devices. Each of the macrocells is typically fully connected to the others in the device. Most SPLDs use either fuses or non-volatile memory cells such as EPROM, EEPROM, or FLASH to define the functionality.
CPLD - Complex Programmable Logic Device
Also known as:
- EPLD (Erasable Programmable Logic Device)
- PEEL
- EEPLD (Electrically-Erasable Programmable Logic Device)
- MAX (Multiple Array matriX, Altera)
CPLDs are similar to SPLDs except that they are significantly higher capacity. A typical CPLD is the equivalent of two to 64 SPLDs. A CPLD typically contains from tens to a few hundred macrocells. A group of eight to 16 macrocells is typically grouped together into a larger function block. The macrocells within a function block are usually fully connected. If a device contains multiple function blocks, then the function blocks are further interconnected. Not all CPLDs are fully connected between function blocks-this is vendor and family specific. Less that 100% connection between function blocks means that there is a chance that the device will not route or may have problems keeping the same pinout between design revisions.
In concept, CPLDs consist of multiple PAL-like logic blocks interconnected together via a programmable switch matrix. Typically, each logic block contains 4 to 16 macrocells, depending on the architecture.
It is something that you will have to look for on ask.com because no body knows w2hat you are talking about
Elasticity is a physical propery of materials which permit the return to the initial state after the cessation of a deforming action.
Is possible to put 3 phase transformer primary as secondary and secondary as primary?
A: The only way can be possible if the transformer is an isolation type.
Yes, you can put the input into the secondary side. This will create a step-up transformer.
What is difference between 2 ohm and 4 ohm sub-woofers?
It is the impedence (coil resistence)normally sub component (drivers)are in 8 ohms impedence.2 in parralel is 4 ohms and 4 in parralel makes it 2 ohms.
What is electrical tilt in GSM antenna?
Electrical tilt is a tilt which gives by knob present downward in GSM antenna.
It is done for effecting the coverage of antenna. If one GSM antenna overshoots then interference will produce.
then we give electrical tilt then front lobe will change and back lobe will not change.
so antenna provides coverage in both direction.
Electrical tilt is always gives in City.
It reduces interference.
What is the difference between homologues and analogues?
homologues= same function different origin
analogues= same origin with possibly a different function
Why output voltage increases when capacitive loading is used?
The output voltage do not really increase, it is only the meter reading that increase, because not all meters is true RMS meters. If a true RMS meter is used, the output voltage will read the same with or without a capacitor. A value of .2887 approximately have to be added per volt that is measured on an ordinary meter, the reason for this is that a unsmoothed rectified sine wave is not a pure DC voltage it is a series of half cycles that can be beter explained with a sketch http://www.patenttrade.net/rms.htm
It's a part that reacts by putting out a voltage when a light is shining on it.
Where is location of date code on IC?
usually the date code of a chip is on the "top" side, so that it is visible after it is soldered to a circuit board. normally, the date code is of the form YRWK, where YR is the last two digits of the year, and WK the week number within that year. for example, 1003 is the date code for the third week of 2010.
Confirmed LC, or confirmed Letter of Credit, is a financial instrument used in international trade that guarantees payment to the seller, provided that the terms of the credit are met. It involves a second bank, usually in the seller's country, that adds its confirmation to the credit issued by the buyer's bank, thereby assuming payment risk. This additional confirmation enhances the seller's security, ensuring they will receive payment as long as they comply with the specified conditions.
What is in line recording on a VCR?
Inline recording means that you're using the video and audio input connectors on the VCR to get the sound and picture information, instead of using the built-in tuner. Most VCR's have line in and line out connectors. The red connector is for the right channel sound, the white is for the left. The yellow is for the video in and out.
Name the basic components used in floor framing?
In a conventionally framed wood structure, you will find box/rim joists, floor joists, headers, braces, and some form of decking. There are many parts to a floor and more ways than one to build one.
In timber framed building, you will find posts, braces, girts, joists, connectors, and other heavy timbers.
How do you convert fuel energy into heat energy?
When you burn the gas, it explodes, and creates energy.
Can a low pass filter be used as an integrator?
When a low pass filter is used with a sine wave input, the output is also a sine wave. The output will be reduced in amplitude and phase shifted when the frequency is high, but it is still a sine wave. This is not the case for square or triangular wave inputs. For non-sinusoidal inputs the circuit is called an integrator.
