What type of transistors can be used in an ECM to switch diesel engine electronic unit injectors?
ECMs use large scale integrated circuits that are usually embedded in epoxy. They do not contain discrete transistors and are generally not designed to be serviced.
What is the symbol for a transistor?
There are many types of transistors, starting out with the typical Base-Collector-Emmitter type. There are two types, starting with the NPN type, The symbol for these is PNP There are also the FET or Field Effect Transistors and their symbols are below, as well as the PNP and NPN. The FET's are divided into the N channel and J channel types:
What type of antenna is used in cellphone for FM?
LNA - Low Noise Amplifier
Why junction field effect transistor is called as unipolar devices?
Field Effect Transistors (both JFET & MOSFET) are unipolar because they use only one type of current carrier (electrons in N-channel or holes in P-channel), unlike bipolar transistors (both junction & the obsolete point contact) which always use both types of current carriers.
What is difference between npn ans pnp transistor?
NPN and PNP transistors function in essentially the same way. The power supply polarities are simply reversed for each type. The only major difference between the two types is that the NPN transistor has a higher frequency response than the PNP-because electron flow is faster than hole flow. Therefore high frequency applications will utilize NPN transistors.

What type of technology used in each computer generations?
transistors
What is sound a type of?
Sound is a type of noise.
What type of transistor is used in amplifier?
Depends on the type of amplifier. There are a lot of different circuits of amplifiers and each one of them use proper transistors, that works better for that circuit. Moreover, on every stage of the amplifier are used different transistors as well.
What type of microprocessor contains 42000000 transitors in the same thumbnail sized piece of silicon?
A Pentium 4 contains 42 million transistors. Forty-two million transistors isn't very many--the highest-end Itaniums and Xeons have nearly two BILLION transistors.
Noise pollution in the neighbourhood?
One type of noise pollution in the neighborhood would include loud music. Another type of noise pollution would be loud cars.
Type of circuit may contain thousands of tiny transistors?
"Integrated circuit" (IC, or "chip")
What are the different types of noise in communication systems?
There are a number of ways to classify noise. It can be subdivided according to type, source, effect, or relation to the receiver, depending on circumstances. In order to make the classification more compact, noise sources can be divided into two main groups: • Noise whose sources are external to the receiver (External Noise) and • Noise source created within the receiver itself (Internal Noise). types include: Shot noise; Johnson noise and Partition noise.In electrical terms, noise is defined as the unwanted form of energy which tends to interface with the proper reception and the reproduction of transmitted signals. Electronic Devices unwanted random addition to the signal are considered as Noise.Classification of Noise:There are several way to classify Noise, but conveniently Noise is classified as1) External Noise2) Internal NoiseExternal Noise:External noise is defined as the type of Noise which is general externally due to communicationsystem. External Noise are analysed qualitatively. Now, External Noise may be classified asa) Atmospheric Noise : Atmospheric Noise is also known as static noise which is the natural source of disturbance caused by lightning, discharge in thunderstorm and the natural disturbances occurring in the nature.b) Industrial Noise : Sources of Industrial noise are auto-mobiles, aircraft, ignition of electric motors and switching gear. The main cause of Industrial noise is High voltage wires. These noises is generally produced by the discharge present in the operations.c) Extraterrestrial Noise : Extraterrestrial Noise exist on the basis of their originating source. They are subdivided intoi) Solar Noiseii) Cosmic NoiseInternal Noise:Internal Noise are the type of Noise which are generated internally or within the Communication System or in the receiver. They may be treated qualitatively and can also be reduced or minimized by the proper designing of the system. Internal Noises are classified as1) Shot Noise : These Noise are generally arises in the active devices due to the random behaviour of Charge particles or carries. In case of electron tube, shot Noise is produces due to the random emission of electron form cathodes.2) Partition Noise : When a circuit is to divide in between two or more paths then the noise generated is known as Partition noise. The reason for the generation is random fluctuation in the division.3) Low- Frequency Noise : They are also known as FLICKER NOISE. These type of noise are generally observed at a frequency range below few kHz. Power spectral density of these noise increases with the decrease in frequency. That why the name is given Low- Frequency Noise.4) High- Frequency Noise : These noises are also known TRANSIT- TIME Noise. They are observed in the semi-conductor devices when the transit time of a charge carrier while crossing a junction is compared with the time period of that signal.5) Thermal Noise : Thermal Noise are random and often referred as White Noise or Johnson Noise. Thermal noise are generally observed in the resistor or the sensitive resistive components of a complex impedance due to the random and rapid movement of molecules or atoms or electrons.Get more details from http://blog.oureducation.in/types-of-noise/
