No, the doping profile is entirely wrong. Also some transistors have very low reverse breakdown voltage on the BE junction and will burn out!

You need a TV signal splitter. They're cheap and available just about everywhere, like Walmart, K-Mart, electronics stores. Just split the `antenna out' connection from the cable box. You'll also need a couple more signal wires (coaxial cables) otherwise you'll be two wires short of having what you need. One from the cable box to the splitter and then one for each TV.

It's an electronic circuit that converts digital signals to analog signals. It finds application in something like, say, an iPod. The tunes are stored digitally, and the next-to-last stage, the D-to-A converter makes the aforementioned conversion. Then a little audio (analog) amplifier pumps up the signal and drives the headphones. Bach, Beethoven or Brahms? A helpful link is provided.

The unit of power is watts, the unit of current is amps, and the unit of voltage it volts.

Power = Voltage X Current

Voltage = Power / Current

Current = Power / Voltage

In electricity, power is symbolized with a P, current with an I, and voltage with a V. The real formula looks like:

P = V x I

V = P / I

I = P / V

V = I * R. 1.5 = 8*I
The current flow is 3/16 Amps.

A power regulator or a voltage regulator generates a fixed output voltage of a preset magnitude that remains constant regardless of changes to its input voltage or load conditions.

If were talking about a battery cap for a car stereo, it would be less light dimming and better hits from your woofers. Otherwise you need a voltage meter or something, I have no clue other than my first sentence.

That question hurt my bobble sack.....

A dedicated logic circuit is generally used to perform one task. Not usually programmable. Say for example a lift (elevator) control; where inputs are received from the lift position, door position, floor etc and logic outputs to motors etc from the logic performed.

Multimeter test leads can be purchased at specialty stores like Radio Shack or some larger hardware stores. They can also be found online at Amazon and eBay.

an RC coupled amplifier is basically used for voltage amplification , where the circuit

currents are quite low. higher currents & voltages would mean more dissipation in the

load resistors , which is essentially very lossy . The coupling amplitude to the next

stage is ideally the same as the previous stage signal excursion.

However if a transformer is used for coupling , both large voltages & current can be

handled without incurring the dissipation of a resistive load. Moreover a coupling

gain of the transformer primary to secondary ratio is also a bonus. also because of

the possiblity of correct impedance matching on the primary & secondary side

maximum power coupling is obtained. hence transformer coupling is more efficient

in such applications.

in high frequency applications transformer coupling , along with tuned circuits as

applicable is the choice circuit.

When you dial the mobile number, the majority of the call travels by landline. The mobile network knows the physical location of the mobile handset. Once the call cannot travel by wire any closer, it's broadcast onto the mobile network by a microwave transmitter. It's then relayed from mast-t-mast until it's close enough to the handset to relay directly.

For linear supplies, the straightforward answer is: THE VOLTAGE GOES DOWN.

For regulated unipolar switching supplies (all bets are off), it is likely that your pulse width will increase until you are at the regulated voltage set at the chip. Not all DC supplies behave the same way.

in this the one half of the polarimeter is made of glass and other half of the polarimeter is made of quartz

Growth is electronics and communication has become very beneficial to banking. Banks can now update you right away if they find suspicious activity on your account, saving you from potentially becoming a victim of identity fraud.

and control of current, voltage, temperature, pressure, etc.

ii. For traffic

control and industrial tool control.

iii. For speed control of machines.

There are two standards for high-quality named DVD-Audio (DVD-A) and Super Audio CD (SACD). Players for both types connect to a receiver via a 5.1 channel analog input. So these 7.1 analog inputs are mainly aimed to be compatible with players of those formats.

If you want to transmit 7.1 digital channels to a receiver, you can do that over the HDMI input. You don't need a special audio-only input for that, which is why there is no digital 7.1 audio input standard. HDMI is effectively that standard.

The signals are:

TXD - Transmitted Data

RXD - Received Data

RTS - Request To Send

CTS - Clear To Send

DSR - Data Set Ready

DCD - Data Carrier Detect

SDCD - Secondary received line signal detect

SCTS - Secondary Clear To Send

STD - Secondary Transmitted Data

TC - Transmitter Clock

SRD - Secondary Received Data

RC - Receiver Clock

SRTS - Secondary Request To Send

DTR - Data Terminal Ready

SQ - Signal Quality

RI - Ring Indicator

ETC - External Transmitter Clock

There are also connections for:

FG - Frame protective Ground

SG - Signal Ground

Depending upon application most signals are not used; many just use TXD, RXD and SG.

For use with a modem the lines used could be: RI, DTR, DCD, DSR, RTS, CTS, TXD, RXD, SG.

pls can someone help me with a code or giudeline on this project am currently working on.

my project is on reading data from a microcontroller (89s52) via serialport to Eight textboxes on a PC GUI using C#,am using Visual studio 2008.Am having problems on how to display the ASCII characters e.g(55,23,12,34,42,33,22,23,N 55,23,12,34,42,33,22,23,N,55,etc),also be able to store the read data into an access database using C#.
