What does class D amplification mean?
Class-D amplification is where the amplifiers act as electronic switches.
Within a CPU a transistor act as?
In a microprocessor, field-effect transistors behave as electrically-controlled switches.
When are series circuits useful-?
when loads act as switches
What configuration will give both voltage and current gain simultaneously?
amplifiers operated with Common emmitter configuration for bipolar transistors , will give both voltage & current gain . Though equivalent fet & mosfet circuit topologies exist , these amplifiers operate more on signal voltage on input & the signal current is negligible compared to a bipolar transistor.
Knee pont voltage- briefly distinguish?
The knee point voltage of a CT is the voltage at the "knee" of a I-V characteristic (if you increase voltage, and plot this voltage with respect to the current flow, you will see a logorithmic type response). The knee is usually specified as 10% distortion (ie, the voltage is 10% less than you would expect relative to the current flow). beyond the knee point, the CT is considered in saturation. This applies to amplifiers / transistors as well as CTs. Transistors used as ampifiers are operated in the "linear region", or the region below the knee point of that particular transistors I-V characteristic.
What are the different components?
Transistors,diode,vacume tubes and amplifiers
What are power transistors?
Power transistors are transistors that are used in high-power amplifiers and power supplies.
What does class D amplification mean?
Class-D amplification is where the amplifiers act as electronic switches.
Why are npn transistors used more often than pnp transistors?
The primary reason that NPN transistors are used more often than PNP transistors is that they usually operate faster (at higher frequencies) because the mobility of the current carriers in NPN transistors (electrons) is much higher than that of the current carriers in PNP transistors (holes).
Is it emitter-base junction should be reversed for both npn and pnp transistors acts as a amplifiers?
no, the emitter base junction should be foward for both npn and pnp to act as amplifiers.
In electronic what are the devices that act as switches to allow for computation of binary values?
Nowadays, transistors are mainly used.
Within a CPU a transistor act as?
In a microprocessor, field-effect transistors behave as electrically-controlled switches.
What has the author Norm Dye written?
Norm Dye has written: 'Radio frequency transistors' -- subject(s): Power transistors, Radio frequency Amplifiers, Transistor amplifiers, Transistor radio transmitters
What are the different Active components?
Transistors,diode,vacume tubes and amplifiers
What property of the materials used in computer chips makes them useful as switches that turn electric current on and off?
They are semiconductors and their electrical properties can be very precisely controlled by adding dopant impurities to create a wide variety of components integrated into one chip. Transistors of various types created by this doping process can act as switches or amplifiers depending on the other components integrated around them and connected to them.
What are transistors used in?
Transistors are used in any electrical somponent including amplifiers, remote controls etc.
What are the switches that make up a microprocessor called?
chips
