the usual semiconductor rectifier used in the microwave band is a gunn diode. Vacuum tube diodes are sometimes used too.

Embedded systems can be run on very limited hardware and do not require a lot of extra "stuff" around. This also makes them excellent candidates as mobile systems.

Life is full of disruptive sounds and noises, such as honking car horns, barking dogs, noisy neighbors, annoying snoring and screaming sirens. Unlike playing music in such instances, white noise does not add to the clamor of noise. Instead, white noise contains equal frequencies of all sounds. Research has shown that a steady, monotonous stream of the same peaceful sound, such as white noise, can filter and mask distracting noises. The same soothing sonic benefits of white noise are quite effective in creating the right ambience for both parent and child to enable a safe yet natural sleep. Among their recommendations for alleviating tinnitus symptoms, many audiologists and the American Academy of Otolaryngology - Head and Neck Surgery suggest masking the ringing sound: play a competing sound at a constant low level, such white noise, to mask the tinnitus and make it less noticeable. The Hyperacusis Network notes that "White noise contains all frequencies, and therefore very gently stimulates all the nerve cells in the these subconscious networks, allowing them to be more easily programmed, or reset, so that tinnitus signals are no longer detected. It also reduces the contrast between tinnitus and otherwise total silence." Fromhttp://www.PureWhiteNoise.com

YES it is linear. It is a passive device classified as linear however as frequency increases its behavior will change.

Ohms can be found by using these formulas. Ohms = Volts/Amps, Ohms = (Volts (squared))/Watts, Ohms = Watts/(Amps (squared)).

When two statements have the same truth values: e.g. (All men are mortal, No men are not mortal) (No men are brutes, all men are not brutes) (All men are mortal, It is not true that some men are not mortal) (No brute is rational, it is not true that some brute is rational) (Some animal is a fish, it is not true that no animal is a fish) (Some animal is not a fish, it is not true that all animals are fish) etc... the two statements within each set of brackets are equipollent. They are true together and false together. The word equipollence etymologically means 'equal power'.

Yes. But a motorcycle is a relatively small target. Depending on the radar and the circumstances, it might be possible to argue something like "look past" error. But fighting a radar ticket can be difficult. There are other related questions on WikiAnswers on radar-based citations.

Why does mobile phone time resets to 9.00 pm when remove the battery and then restarts mobile phone?

power is = V2/R

so

40x40= (230)2/R

R= 33.25

now

V= IR

where I is current

230= IXR

I= 230/33.25

= 6.9 amp

the op amp is a one IC which does not work at hige volteg so the IC not consumed the high frequncy

You can consider a short circuit to be a resistor with R=0 Ohms. It is then clear by the equation for calculation of parallel resistance that the combined resistance of a resistor in parallel to a short circuit is 0.

Consider the following example with R1= 1k Ohms and R2= 0 Ohms:

Rtotal = R1*R2 / (R1+R2) = R1*0 / R1 = 0 Ohms.

as the name suggest transistor means to transfer resistor, it is an electronic device,

An adder-subtractor is a circuit capable of subtracting or adding binary numbers. The application of a 4-bit adder and subtractor is for use as part of the core of an ALU, or arithmetic logic unit.

Absolutely.

yes

A rigid flex printed circuit board is used in some specialized electronics equipment. Some examples of electronics that use this form of circuit board include military equipment and cell phones.

The advantage is most of the circuit has already been connected up for you and you only have to add a dc power supply and couple of components to set what frequency you want it to work at.

A typical multimeter measures voltage and resistance "in parallel" or current in-line with the circuit.

It all depends on the model. 'Multi' means many different modes. Some have more than others.

Some multimeters can measure current, but require you to alter the lead configuration and plug into different sockets.

If you have the meter set for Current measurement and you put it in parallel instead of series, it will cause a dead short and could damage the meter. (They usually have a fuse inside for protection).

Knowing any two of the three parameters you can calculate the third by Ohm's Law: Voltage = Current x Resistance.

Knowing Current and Voltage you can calculate power as Volts x Amps = Watts for resistance loads.

If you mean how to use a resistance of so much power then it can be easily done through a step-down transformer which lowers the voltage supply and hence the power.

You can't do that calculation given only that data. It depends more on the design of the LED than its drive levels.

Good question! The Malebioncy is usually only talked about in higher level courses. The Malebioncy is defined as the ability of the calculator to switch from on to off in rapid periods of time.
