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 a person can earth a conductor?
Inside a building, you connect the conductor to the AC outlet ground (the circular hole in the wall outlet). Outside the building, the conductor can be connected (soldered, for example) to a copper pipe which has more than six feet underground in soil.
Warning: never work with electricity, no matter that it is just for a second, unless you have taken safety classes and basic lessons in electricity. People go to school to be an electrician.
What is a home run connection?
Typically, I've heard this term used by industrial electricians. It means that a single cable, or single conductor is used to connect a device at one end, and the other end of the wire is connected directly to where it needs to be.
For example; a temperature probe (in a large industrial cookie oven) has one cable connected to it, and the other end of the cable goes directly to the device that monitors the oven temperature. There are no junction boxes, wire nuts, or splices used anywhere for a device's wiring connection. Make sense???
What is the relationship between wafers and semiconductors?
Semiconductors of various designs are etched onto wafers of silicon. Those wafers are then tested to find out how many of the semiconductors have formed workable intergrated circuits. The wafer is then cut up into individual chips of intergrated circuits with the workable chips going further on in manufacuring and the non working chips either being dumped or pushed aside to lower speed chip manufacturing.
What are the two levels of of esd sensitivity?
According to 00-25-234, para. 7-4 its sensitive and super sensitive
What is meant by single side band modulation?
Single side band suppressed carrier modulation is like amplitude modulation except that one of the sidebands is suppressed or filtered out. Each sideband carries the same though opposite, information, so suppressing the one sideband allows more power to be placed into the one remaining sideband. The downside, of course, is that the demodulation process is more complex.
What is the purpose of an anti static wrist strap?
Believe it or not, static electricity can be very high and this can destroy sensitive IC chips easily. I've seen new ones handled improperly and installed only to find them bad.
How can you add numbers in base n?
Easy solution
1. Convert numbers to base 10
2. Add
3. Convert result to base n
To add without converting, follow these steps Adding 2 Numbers in a Different Base:
A. Adding numbers in a different base is similar to adding numbers in base 10.
1. Add the one's digits first like you would in base 10.
2. If the number is less than the base, write it down. If the number is greater than
or equal to the base, you must carry. So find the remainder after dividing by
the base and write it down (i.e. n MOD b) and to find the number you should
carry, find out how many times b will go into n (i.e. n DIV b).
3. Continue adding the next digits as described in step 2 until all numbers are
added. Don't forget to add in any carried numbers.
4. Note: You must add the digits from the right to left. In other words, add the
ones digit first, followed by the tens digit, and so on.
Ex [1] 143
5
+ 41
5
=_________
5
.
a. 3 + 1 = 4. Since 4 is less than 5, write it down.
b. 4 + 4 = 8. Since 8 is greater than 5, we must carry. 8 Mod 5 = 3.
Write down 3. 8 DIV 5 = 1. Carry the *1.
c. 1 + *1 = 2. Since 2 is less than 5, write it down.
d. The answer is 234.
Ex [2] 222
3

3
+ 220
3
=________
3
.
a. 2 + 1 + 0 = 3. Since 3 is equal to 3, we must carry. 3 MOD 3 = 0.
Write this down. 3 DIV 3 = 1. Carry *1.
b. 2 + 2 + 2 = 6 + *1 = 7. Since 7 is greater than 3, we must carry.
7 MOD 3 = 1. Write down 1. 7 DIV 3 = 2. Carry *2.
c. 2 + 1 + 2 = 5 + *2 = 7. Since 7 is greater than 3, we must carry.
7 MOD 3 = 1. Write down 1. 7 DIV 3 = 2. Since there are no
more numbers we can just write down 2.
d. The answer is 2110.
>Very simply, you modulate a signal to carry a message.
While a message can be carried over the airwaves without modulation, a modulated signal requires less power to transmit and a smaller antenna due to the higher frequency of the carrier wave. Modulation also lets many different radio, TV, cell phone, etc. users send messages over the airwaves without interfering with each other.
Answer - a bit moreIt is said that a carrier alone conveys no information (think about it).However, that's not entirely true.
An unmodulated carrier tells me that at least a transmitter is active/working. Other things may be inferred from that.
You've specified a distance, but no force. Any answer is correct without a force specified.
How can I artificially create electromagnetic radiation?
I'm working on a science project where I need some form of artificial electromagnetic energy. I've heard that a coil produces some radiation but I don't know much about electronics and need an easy way to create some ER.
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.

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.
