Usually copper, sometimes gold or silver.

adding resistors to a string will have the effect of decreasing each resistor voltage drop.

the cell will add all of the voltages to a lump sum.

Say there are n possible input sequences that is A1 to An. Coded sequence B is transmitted. At receiver end due to noise sequence R is obtained. Than we will calculate P(Ai/R) for i = 1 to n. Decoded sequence A for which the probability is maximum is decoded maximum likelihood sequence.

It will expand to fit the ear to close all inputs

A PLL is different than a VCO. Each has its own use.

Actually a PLL (Phase Locked Loop) contains a VCO (Voltage controlled oscillator).

A VCO is an oscillator whose frequency is related to an input voltage. You can use it when you need a varying frequency that is controlled by a varying voltage. But it is not great at outputting a consistant exact voltage because it is very sensitive to its environment (e.g. temperature).

A PLL will "lock" its output frequency to some input frequency. So it can oscillate at a frequency that is controlled by an input oscillator. Not too useful if the output frequency is the same as the input. But the output frequency can be divided before it is compared to the input. This allows the output frequency to be higher (some multiple of) the input frequency. Once a PLL is "locked on" to an input frequency it can be very stable.

Voltage and current are two different things.

Voltage is the electric potential difference between two points. Expressed in volts, it is also joules per coulomb.

Current is the charge flow past a point. Expressed in amperes, it is also coulombs per second.

You can relate voltage and current using Ohm's Law, which states that voltage is equal to current times resistance.

Resistance is, therefore, equal to voltage divided by current. Using base units, resistance is equal to joules per coulomb divided by coulombs per second, which simplifies to joule-seconds per coulomb squared. That is a difficult unit to write, so we just use ohms as the unit.

Read about logic ring counters.

A voltage buffer is a circuit that will buffer a source from an output.

it all depends on its open loop gain or crossing the zero db point at slope less the -1db

ZENER DIODE IS MADE TO REVERSE BREAK OVER AT A CERTAIN VOLTAGE the break over knee is not exactly sharp especially in low voltage zeners. and p-n means positive and negative junction

Motion detectors have had a massive impact on today's society. Motion detectors have made life easier for those who are very busy for example.

1) It greatly simplifies the design of the low pass filter which follows the DAC, which has to attenuate the aliasing noise but not the signal. Oversampling increases the gap between these, simplifying the low pass filter.

2) It allows for interpolation and thus much lower sine wave distortion figures.

3) It allows for superior DAC architectures such as delta-sigma and 1 bit DACs.

I am not to sure about Static Ram but in CMOS RAM, 1GB of RAM would contain about 137438953472 transistors because 1 bit of CMOS RAM contains 16 Transistors, 8 bits in a byte and 1073741824 bytes in a gigabyte.

I am 100% sure about this and these are just estimations.

Static RAM uses about 6 times as many transistors as dynamic RAM for the same amount of storage. Dynamic RAM uses 1 or 2 transistors per bit in typical implementations. Add to this transistors for address decode, bus interface, etc.

It is device that will sense the environment in a form of capacitor changes. Usually an oscillator will sense this change and change frequency accordingly

A transformer can never be an ideal device to transfer power. Its inherent design has limitations caused by losses WITHIN the device itself.

what is the other name of common emitter amplifier

Where can I get copy explaining what the symbols mean on a sperry multimeter and how to use them.

It is almost equal to zero volts because no device in this universe can amplify the power --output will be in confine to millivolt or less due to applied magnitude of input signal and ambient noise

according to principle Energy can't be created nor destroyed it can only be transferred from one form to another form.

Some Integrated circuits are chips that can be programmed to customiise them to a particular requirement laid down by the designer.They are now in many forms Some can be electrically programmed with binary data in the form of Hexadecimal notation or machine code. This is known as an EPROM Some newer chips can be programmed via an interpreter in a high level language.These are the new universal chips known as PICS. These have taken over as single chip controllers of microwave ovens and washing machines for example.Software can be erased and upgraded as the product develops and this is done electrically rather than having to use Ultra Violet light as in the EPROM. The chips are supplied by the manufacturer in an unprogrammed state and they are then usually placed into a PROM programmer and 'blown' by the programmer according to the binary data you have asked it to load. The programmed chip is checked and then placed into a socket on it's circuit board and is able to direct the operation of a microprocessor.

PICS are treated the same way and then slotted into the target board but can be reprogrammed in situ if a software upgrade is necessary.
