This is an abbreviation for gigabaud; a giga prefix is equivalent to one thousand million and baud is measure using in information theory and datacomms and indicates symbols per second. So 1 gigabaud is one thousand million symbols per second.

Difference is in the work spot of voltage. Because of that, difference is in the graphics too. Also, angle(A)>180 , 90<angle(B)<180, angle(C)<90

Gold is the best conductore

laboratory experiments

Electricians use them to view signal voltages, usually as a two-dimensional graph of one or more electrical potential differences (vertical axis) plotted as a function of time or of some other voltage (horizontal axis).

Oscilloscopes are used in the sciences, medicine, engineering, telecommunications, and industry.

Special-purpose oscilloscopes may be used for such purposes as analyzing an automotive ignition system, or to display the waveform of the heartbeat.

When reliability is concerned then ICCP method is superior but when overhead cost incurred in installation and maintenance is concerned then sacrificing anode method is better than ICCP method.

Think of it this way:

"P" is for Positive and "N" is for Negative

So basically put a PNP Transistor Would use N to Switch P, in the name "PNP" or "NPN" the first character is for the polarity of the Collector-pin, the second for the Base-Pin, and the third for the Emmiter-pin.

If you have a NPN Transistor you can`t just replace it with an PNP as the polarities differ. If you can find a way to change those polarities then sure it could work.

I would say it`s best go out and buy a few of both so you have a few, otherwise if the application of the transistor is not in a high-current or high-voltage circuit try and find another circuit with the required type of transistor.

Absolutely most transistors can be replaced with other similar transistors.

Different transistors have different conditions they work by so you should do some research and replace it with another that is either the same or have approximately the same data.

Example 1:

A burned transistor with the data NPN, 45Volt, 100mA, 0,3Watt, need to be replaced.

It is a discontinued transistor, so unfortunately no original spare part can be found.

Check the max voltage of the circuit where it was. If the voltage is close to 35 volt, then you may want to replace it with a higher voltage transistor. If it is lower, say max 20 Volt, then you should be able to replace it with a lower voltage transistor.

Check the type of circuit where it was. If in an audio amplifier, then you should choose a 'low noise' audio transistor.

Look at the NPN transistors you can get hold of and make your choice based on similar or more current, similar or more wattage, similar or lower or even higher voltage.

Most small signal transistors are interchangeable if you follow these steps.

Even most power transistors are interchangeable but you should make an extra effort and check/match the HFE Data on the transistor too. Normally no need for an exact match at all.

Silicone grease is a waterproof grease made by combining a silicone oil with a thickener. Most commonly, the silicone oil is polydimethylsiloxane and the thickener is amorphous fumed silica. Using this formulation, silicone grease is a translucent white viscous paste, with exact properties dependent on the type and proportion of the components.

When your audio modulating signal is larger than your RF carrier amplitude the peak of the modulated carrier will become flat and a distorted audio signal with flattened peaks will be send out from the detector on the receiver side

Amplified warming involves increased heating and production of CO2 caused by heat that is abnormally high in the atmosphere. There are many more greenhouse gases being released causing additional warmth to Earth and the atmosphere.

The 7483 is a 4 bit full adder and a 0 on C will make it act as a subtractor

the ic is a semiconductor chip which is perform some function according to need and other word it's a precise form of any biger ckt's

The letters i.c. are the abbreviation for integrated circuit.

PSPICE stands for Personal Computer Simulation Program with Integrated Circuit Emphasis

Make the device very small, so that the capacitance of the device is small

I would definitely check the Mesa/Boogie website, they generally have lots of stuff like that : )

convert signal gains or losses to comparative decible reading.

The op amp is an electronic device consisting of a complex arrangement of resistors, transistors, capacitors, and diodes. Here is a link to a 741 Op-Amp design...

Connected in parallel with the system to reduce overcurrent/losses

An AC (non-polarized), usually high voltage capacitor that is connected in

parallel with an inductive Motor (and very close to the motor, or other

inductive load) to help reduce Reactive Power (Magnetizing AMPS)

which do no real work but only cause extra heat in the wiring and motor

as there is a Lagging Current Phase Angle created by an Inductor and a

Leading Current Phase Angle created by a capacitor which helps correct

the impedance mismatch between line and load.

Google "Reactive Power" and/or "ELI ICE man" for more information.
