Electronics Engineering

current flow is proportional to the voltage and inversly proportional to the resistance

The voltage drop along the slide wire of potentiometer can be controlled by adjusting the value of working current. The process of adjusting the working current so as to match the voltage drop across the portion of sliding wire against standard reference source is known as standardisation

integrator converts the quantised signal to saw tooth signal which then compared with the present signal and error signal is generated,and error signal is quantised and the process continues

By deciding to study so as to become an electronics engineer. Then you can learn how to design and fabricate integrated circuits.

Part of your course of study and practical experience training would be to learn how to use the appropriate hardware and software tools so as to be able to code and decode integrated circuits.

* Flexibility of deployment across various frequency bands with little needed modification to the air interface. * Averaging interferences from neighboring cells, by using different basic carrier permutations between users in different cells. * Interferences within the cell are averaged by using allocation with cyclic permutations. * Enables orthogonality in the uplink by synchronizing users in time and frequency. * Enables Single Frequency Network coverage, where coverage problem exists and gives excellent coverage. * Enables adaptive carrier allocation in multiplication of 23 carriers = nX23 carriers up to 1587 carriers (all data carriers). * Offers Frequency diversity by spreading the carriers all over the used spectrum. * Offers Time diversity by optional interleaving of carrier groups in time. * Using the cell capacity to the utmost by adaptively using the highest modulation a user can use, this is allowed by the gain added when less carriers are allocated (up to 18dB gain for 23 carrier allocation instead of 1587 carriers), therefore gaining in overall cell capacity.

Squelch is something used in telecommunications, squelch is a circuit function that acts to suppress the audio (or video) output of a receiver in the absence of a sufficiently strong desired input signal. For instance if you turn the squelch up on a radio you can cut out the noise but if someone transmits they will pass the squelch threshold and be heard.

A capacitor is a device that stores electric potential energy and charge. Unlike batteries, capacitors do not involve chemical reactions. They merely encompass the movement of charged particles, so they can be charged and discharged very quickly. This important property gives them many useful applications.

They are used as electrical flash units in photography, lasers, air bag sensors, radio receivers, and television receivers. Most importantly, they are used in alternating-current circuits, which play a crucial role in most household and industrial power-distribution systems.

In general, the way to reduce effective Q in a parallel RLC circuit is to reduce the value of R.

A room usually full of connected computers, LAN standing for Local Area Network means all the computers contained within, and sometimes a few near by, all are talking to one another to create a small web of computers. This is most often used for playing games with friends in a close space.

Voltage stabilizers are the circuits that are used to filter noise from the source voltage. DC voltage generated from a bridge network or diode network will contains voltage glitches. These glitches may cause serious problems to the operation of digital circuits. So a voltage regulator is used to filter these glitches. voltage stabilizer can be built using a voltage regulator ICs like 7805 for +5V, 7809 for +9V, 7905 for -5V, 7909 for -9V and so on.

The current supplied to the filament for heating is defined as the Filament current.

whereas

When the filament is heated to a high temperature, the electrons are emitted. The flow of electrons form Cathode to anode is the tube Current.

It is the fraction of minority carriers injected into the base of a BJT that successfully diffuse across the quasineutral width of the base and enter the collector. Ideally, it should be as close to 1 as possible, for maximum amplification. It is usually represented by alpha_T. alpha_T = I_C/I_E, where I_C is collector current, and I_E is emitter current. For an NPN transistor I_C and I_E are electron current, where as for a PNP they are hole currents.

To make a full subtractor, you need an XOR and a NAND gate.

Microphone gives ac output.

Microphone converts sound energy to electrical energy. Due to vibration of Carbon diaphragm the resistance varies so that the amplitude of current varies.

That is not entirely true. A microphone element produces a very small DC sine wave output, all of it above the zero line. It can be made to have an AC ouput if a circuit is added to do so, as an amplifier which provides the negative component. Thus, half (or sometimes less than half) of the sine wave will be below the zero line. Otherwise, circuitry may be integral to the mic.
