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.

Two words mega from Greek meaning a quantity and diversity is just that.
A pps signal stands for pulse per second. It is electric and repeats one every second. Pulse per second is mostly involved in health care; for example, nursing.
You open one of the leads of resistor connected in electronic circuit while measuring its resistance in order to not introduce error cause by other components in the circuit.
4 bit combinational circuit decrementer using full adders?
Use the regular 4 bit full added, but make one of the inputs 1111 = 2's complimentrepresentation of -1. This will serve to decrement the other number by 1. Throw away the 5th bit, the carry bit.
Example
If 5 is entered:
0101
+ 1111
______
0100 = 4

What is the minimam distance of IS cable and non IS cable in same tray or trench?
It should add a divider between this different type cable to prevent the interference Type your answer here...
What is the function of the CD4017 IC?
It is a MOS decade counter/divider. CD4017 consist of 5 stages Johnson counter and an output decoder that converts the Johnson binary code to a decimal number.
Why does my TO-220 LM7805 regulator need an insulator before a heat sink?
The case of the TO-220 LM7805 regulator is device ground. If the heatsink is also ground, you do not need an insulator. If the heatsink is not ground, or if you need to maintain distinct grounds, or if the LM7805 ground is something else besides ground, you need an insulator. Its up to you, since you are responsible for system and circuit design.
What is the difference between on and off state resistance?
On Circuit Resistance = Close to the total load Resistance.
Off Circuit Resistance = Near Infinitive High Resistance.
Advantage of critical damping over under damping and over damping?
A system that is critically damped will return to zero more quickly than an overdamped or underdamped system. Underdamping will result in oscillations for an extended period of time, and while overdamped things will return to zero without much (or any, I think) oscillations they will get there more slowly.
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.
Give example of primary secondary cells?
A primary cell can't be recharged, for example am ordinary 'D' cell, while secondary cells are rechargeable, e.g. one of the cells in a car battery.
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 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 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 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

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
.
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.
