ASCII is very common. EMBDIC is hardly so.

However, ASCII has been almost completely replaced by Unicode, which is by far the most common encoding scheme anywhere. Unicode comes with several variations (UTF-8, UTF-16, UTF-32, etc). UTF-8 is an 8-bit extension of the 7-bit ASCII coding scheme and allows the encoding of any arbitrary character available in Unicode. The different formats UTF-16 and on are primarily used to encode characters in a different language that will almost always require subsequent bytes.

There are dozens of different types of antennae. To see a list and get more details about individual types, see the related link.

The easiest way is by using an FET

Ground is a base point in every circuit.we define it's potential to 0.so GND=0 Volts.

We know that logical circuits build up with transistors and use those in saturation mode. in saturation mode we need 5 volts voltage in input to we have this mode.5 volt voltage is IC working voltage(Vcc) too. so 3-5 volt is 1 logic

A triode pentode is a thermionic valve, also known as a vacuum tube (USA). It comprises a triode which has three electrodes and a pentode which has five electrodes, both sections of the valve are enclosed in a single glass envelope.

They were often used in domestic audio amplifiers in the 'valve era' where the triode section acted as a preamplifier to increase the amplitude of the low level signal from the input source such as a tape head or a crystal pick-up; and the pentode section provided sufficient power amplification to drive a small loudspeaker.

Minimising the number of valves in such designs significantly reduced the overall power consumption, heat dissipation and manufacturing cost of the equipment. It also reduced the retail price, making record players more affordable to the domestic consumer.

Triode pentodes are still used in some current production, British built Hi Fi amplifiers because, with careful attention to the design, they can be configured to out-perform double triodes (two triodes in a single envelope) in the driver stages.

Typical D cell batteries NiCad or otherwise are 1.2 volts.

that is called solar cell which converts light(photons) to D.C voltage .the amplitude of voltage depend on how many solar cell are you joined in seies a solar cell normally produce 0.6-0.7 V D.C

If one signal is weaker and the other is stronger, the receiver captures the stronger signal and completely ignores the weaker one, resulting in adequate

reception.

You have the hosts that keep the show going. There are also advertisers and music that are sent over the airwaves. You have the speakers, the airwaves, and the signal to get it to your consumers.

To combine the signals of multiple microphones, you add (sum) their electrical voltages, just like the sound waves from multiple singers sum in the air.

To measure the voltage produced by the microphone without affecting it, you need amplifier circuits with high input impedances. These amplifiers must also have a widely variable gain (trim control), since there are many different microphones with different output levels, and you want them all internally at the same level. Then you might have EQ or other controls to manipulate the sound of each microphone.

Then there is an overall volume control for each microphone, for setting the relative level of each. Then the weighted signals go into a summing amplifier to be added together, and then to an output.

No, the output of monostable multivibrator does not oscillate. As it has only one stable output we do not get oscillations. We get a square wave as output.

This question really needs a little more context, but an attempt would be:

1: Properties common to both NAND and NOR gates:

- they are both electronic logic circuits (as implied by the term "Gate")

- they both compute a primitive single valued Boolean function of two or more input terms

- they both implement the inverted output version of their primitive (the leading 'N')

- there are no families of logic components that implement one and not the other in their catalog

2: differences:

- the NAND output is TRUE iff any of its inputs are FALSE

- the NOR output is FALSE iff any of its inputs are TRUE

- the NAND circuit is much simpler to implement than NOR

(NB: the term 'iff' means 'if and only if' - it is not a typo)

The 7475 is a TTL MSI circuit that contains four D latches, it is also known as 'quad bistable latch.' The 7475 is mostly used for temporary storing 4-bit nibbles of data. Any length of data can be stored by using more than one 7475 chip. When all four clock input pins connected to logic high clock pulse, input data is loaded into the D latches(each latch is D Flip-Flop) and appears at the Q output and remains there. After clock pulse goes logic low, the output at Q and Q' still holds input data till clock pulse changes it logic state back to 'High' and input data is changed.

Not sure about electronics engineering, but I have a feeling it's a medical term. The diaphysis is the shaft of a long bone, the epiphysis is the knobbly bit at the very end. The metaphysis is the bit between the two which is the "growing" bit. I would presume then that the diametaphyseal junction is where the diaphysis and metaphysis join. In short, if you think of a long bone like your thigh bone (the femur), the classic "cartoon" bone with a long straight bit and knobbles either end, then the diametaphyseal junction would be about where the knobbles meet the long straight bit.

Hope that makes sense!

conductivity of semiconductors increases with increase in temperature as breakdown of covalent bonds take place in the semiconductor due to increase in temp but more & more increase in the temp may result in the breakdown or damage of the semiconductor which results in the decrease in conductivity of semiconductor
