Transmission voltages are in multiples of 11 to allow for 10% transmission line losses. Therefore, to obtain 100% efficiency, voltages in multiples of 11 are transmitted.

A binary encoder is a person who creates a code used to program computers at the most basic level. Claude Shanna developed binary encoding in the 1930s.

A protective relay determines frequency of an AC signal of an electric power system. The protective relay includes a circuit measuring the AC signal period between zero crossings to provide a measured period value. A microprocessor includes a random access memory having a five-element array, which collects five consecutive values of the measured period values. A microprocessor routine chooses a median from the measured period values and generally determines the frequency based upon the median. The median is ignored and the previously determined line cycle period is adjusted to determine the new line cycle period if: an absolute value of a difference between a last value of the measured period values and a previously determined line cycle period is not less than a predetermined value; and the last value of the measured period values is within the limits of the array. <Prof Dae_Pwa>

i dnt no m8, that's what im trying to find out its solid.

it is used for reciving the infrared signal of frequency 38khz from a remote location at distance may be 10 m.

The ULN2803 is a small integrated circuit that contains 8 transistor driver channels. Each channel has an input to a resistor connected to the base of a transistor and a 1 amp open collector output capable of handling up to about 30volts (if my memory is correct). Each of the collectors has a reverse biased diode connected to a common Vcc pin that provides inductive spike protection. Typical uses are for micro-processor interfaces to relays, lamps, solenoids and small motors. A 2803 with a set of relays is a simple and effective way of switching mains voltages for example. They are used less commonly today but were once an almost universal means of interfacing processors to power devices.

it causes over modulation .... that is the phase reversal of carrier signal ..... the modulated wave then exhibits envelope distortion which results in loss of data .....

A: an operational amplifier has two input A+ and a - input feeding to a base of a transistor ideally both diodes are matched with a current source to make them equal so basically they are both balanced or virtually at the same potential increasing one potential to one will inversely effect the other.

usually these junctions are transistor base to emitter but it could that one is just a plain diode working on the exponential curve of the diodes

why the out put is equal to the positive power supply of the op amp when the nonenverting aom input is greater then invertung input

SQDCM stands for Safety, Quality, Delivery, Cost & Morale. These form the 5 classes under which related metrics are devised to track the performance of a buisness. These metrics could also be done at department level. The number of accidents could be a metric in Safety. Accordingly targets are devised and benchmark ratings are indicated. These metrics are recorded at frequencies, like monthly or weekly. With recording of current metrics, action plans are also drawn up to correct deviation from targets. All these are recorded in simple formats and displayed openly for perusal of all the stakeholders and outsiders too.

When I found out 20 years ago that all people around me whether at my workplace, friends, neighborhood is practicing and observing NORMS of the society. The result and status of their lives is generally the same (whether a boss or normal employee)but by making a BIG Difference in all facets of my life (of course without breaking the law) -- I can say "NO REGRETS".

Hi, For every GSM band there are Uplink and downlink frequencies. Example: GSM 900 TX: 880 MHz to 915 MHz is an uplink frequency range GSM 900 RX: 925 MHz to 960 MHz is a downlink frequency range Aloha, Maverick

the field of proces control en instrumentation deals with monitoring process parameters en adjust the process (control) based on that information. instrumentation is required to monitor and control the process, and varies from process to process

if i made ear defenders i would :

Use foam because - it will absorb the sound

Use rubber because - it has a lot of air bubbles in it. Sound takes a long time to travel through gases like air . Also some of the sound may reflect off the rubber. airpoo

Vacuums, because sound travels best through air and there would be no air to travel through.

And use cotton wool. : )

what is M-ary communication?

This term is often used with electronics and engineering. By definition, the recovery time of a sensor is the time a sensor takes to return to a baseline value after an event.

Cadsoft Is offering Eagle, free with a limitation on the size of the PCB. otherwise it is fully functional and easy to understand and use, see the related link for easy download of Eagle. http://www.cadsoft.de/download.htm

Yes of course,

we have salts, minerals etc....

so they do

The body is not a great conductor, but it can conduct electricity and that is why you can feel a shock through static electricity or a killing shock such as an electric chair. Conductance will vary from person to person and will change depending on conditions such as sweat, being wet from a shower and so forth.

He is the sometimes refferred to as the father of modern Electronics. Akandi Started his Univerty education in the University of Ghana where he made several discoveries.

PCM technique is used to convert analog voice signals into digital. In PCM the analog frequency is first sampled and then converted into binary bits. Each samples are taken as 8bits long.

Basic communication theory requires that a minimum sampling rate of twice the frequency of the signal to be sampled will result in an accurate representation of the original signal.Human voice can have max 4000hz frequency, therefore sampling rate should be 8000 samples/sec.Which implies required bit rate for transmitting voice is

8000*8 = 64000 bits/sec = 64kbps.

Mean has two meaning 1.airthmetic mean 2.Expected value of a random variable which is also called a population mean. in statistics and probability theory it is defined by lambda i.e, the arrival rate of a people in a specified unit of time.

It's the current you have to inject into the device so that the gain inside it is equal to the losses due to absorption and scattering of the light generated. When you have reached this amount of gain, then lasing can start to occur.
