In parallel circuit the current through the resistors are different in values depending upon the values of resistors. But the sum of the currents across all the resistors will be equal to the current through the sourcgsvg bdjasuhafyuhda

the size of an integer is determaind by using the function "sizeof(c)",here 'c' is any integer.

A radar transmitter is the portion of the radar system that generates the high power microwave signal that is transmitted. This is the electromagnetic wave that the radar sends out to see if it will be reflected off anything in the field of the antenna. The transmitter generates the pulse (in a pulsed system) when the control system tells it to, and this high energy pulse leaves the transmitter and goes down the waveguide to the antenna. From there it goes out into the medium being "looked through" by the radar. After a time (during which the receiver is listening for returns), the transmitter is again told to create the next pulse. Some radars use a continuously broadcast signal, but most use the pulse. The above statements are correct but not quite complete as it describes pulsed transmitters only. A Transmitter in Essence is either one of two thing a High-Power Amplifier or a High-Power Signal Source. Transmitter can also be either Pulse Modulated (AM) or Continues Wave (CW) and some timed both. Both of these types can be either phase coherent on non-phase coherent. The first practical transmitter was invented by the British and this transmitter made Radar practical, as until then the effect of signal reflection was known but the power transmitted was so low the practical range was so limited it was of little or no use. For this reason the British are regarded as the innovators of Radar (and the inventor by some). The first practical high power transmitter was a magnetron and it was a RF resonate cavity machined from solid cast metal. The advantages of this transmitter is that it is high power and Pulsed, and allows a low transmit duty radio. However the disadvantage is that it is non-phase coherent and fairly narrow from one pulse to the next; however Magnetrons are still used today in almost all Marine Radars. The next radar transmitter to emerge was a Klystron and a Klystron was a high power amplifier rather then high power signal source like the magnetron. Klystrons where phase coherent but where lower power and narrow band. However since the transmitter was now phase coherent, Fourier integration in the signal processing could be used to provide a higher signal to noise ratio in the detection stage to compensate for the reduction in power. The Klystron design differed from the magnetron by not being a circular resonate cavity like the magnetron but was effetely strained out into a liner length and this fixed length made the Klystron Phase Coherent as the path length was known and the amount of tuning received was equal in every pulse, but the coupling to the path length in the design made it narrow band. The Klystron design was modified to provide a standing wave transmitter know as the Travelling Wave Tube (TWT), The Travelling Wave Tube (or Twit as in known), is a wider band version of the Klystron that still maintained the phase coherency. Today the trend is not to have one single large transmitter but to have thousands of small cooperating ones that transmit individually at a low power but when constructively combined provide a high power source as either Pulses of CW. This technology provides a transmitter and a combined receiver in thousands of modules known as TR Modules and there advantage is no single point of failure and element phase control to electronically steer a radar beam.

Its actually a sine function graph. It illustrates the variation of voltage and current with time. Yeah voltage varies every second in your house, only reason you cant detect it is the high frequency( >60 hz) at which they are transmitted.

the fastest way to transmit data is certainly not coax it is fiber optics u can run city blocks of cable, on one hair size thread of fiber optic hope this is helpful. p.s when transmitting data through coax it takes Amplifiers and A.C. to boost the R>F signal about every three to four city blocks while fiber optics has no A.C and as i said a hair siZe thread can run city blocks

As the frequency increase its penetration power decreases.The signal travels a lesser distance.Hence for a perticular area more no of towers need to be erected in 1800/1900 than in 900MHZ for full coverage...Hence vodafone( 1800MHZ) has more towers per unit area than Idea Cellular ( 1800+900) .....

Band of 900 is from 890-915( uplink) 935-960Mhz( downlink)....

Band of 1800 is from 1710-1785(uplink) and 1805-1880MHZ(Downlink)....

Same property is followed here.....The uplink is lower ( MOBILE -BTS) than the downlink frequency (BTS-MOBILE)...so that this may help the uplink signal to travel futher without consuming much power...BTS due to its increased power ,has higher frequency to tavel the same distance....

The cloud around an atom's nucleus is called an electron cloud. An electromagnetic force binds electrons inside an electrostatic potential well, which surrounds the nucleus.

At the highest level, copper wiring is a better conductor than aluminum, but not as good as silver or gold. It is quite flexible initially, but after much flexing in one place can get brittle. It is more expensive than aluminum.

To get reasonable gain without losing stability of circuit.

ANSWER: Is to reduce the input to a lesser value or to match signals impedance

Amperes

they are made of alluminium

emphasis is when you make something REALLY clear and prominent, like that, either a specific point or part of a word i.e. EmphaSIS

Previously when transmitters were configured for 0-20mA signal it was very difficult to identify an open circuit at 0mA,hence to supersede this defect it was decided to configure the transmitter as 4-20mA signal,so that if there is open signal it can be easily identified.

The Self Bias of the BJT is also called the voltage divider bias. It is called thus because it can stabilize the collector current, the base emitter voltage and the amplification factor.

Parts of a digital multimeter include an LCD display and range knob. There are also common ground, positive voltage terminal, and positive current terminal.

It is a slang tern given to a Differential Pressure Sensor or Transducer.

They allow the user to test: Volts (AC and DC), Amps, Ohms and basic continuity.

The "count" of a multimeter refers to how large a number it can display before it has to change measurement ranges, and how many digits it shows total. This affects how precise a measurement the meter can display (note: this doesn't necessarily reflect absolute accuracy, just precision of the numbers it can report.)

First, the total number of digits of the count matches the digit count of the display.

A x00 count multimeter only displays 3 digits, while a x000 shows 4 digits. So a 200 count meter could read 19.9 volts, while a 2000 could read 19.91 for the same input.

Second, the value of the first digit indicates when the meter needs to "move up" to the next range. A 2000 count multimeter would read 19.99 volts as 19.99, but at 20 would have to read 020.0, loosing a digit of precision. The same thing happens at higher and lower ranges, each time having to move when the top digit reaches 2.

For comparison, a 4000 count multimeter would up-range whenever the top digit gets to 4, allowing it to read 20-39.99 volts with two decimal places where the 2000 cannot.

I suspect, but cannot confirm, the count limits in digital meters are due to the A/D converter used, and the number of output bits it has. This matches up with the common count values being close to powers of two.

Crossover distortion is a type of distortion which is caused by switching between devices driving a load, most often when the devices are matched. It is most commonly seen in complementary, or "push-pull", Class-B amplifier stages, although it is occasionally seen in other types of circuits as well.

In diode some current flows for the presence of the minority charge carriers. This current is known as reverse saturated current. This is generally measured by picoampere.

This current is independent of reverse voltage. It only depends on the thermal excitation of the minority carriers
