Why is it necessary to digitize voice signals?
To minimize the distortion of analog signals during transmission Because digital lines transmit signals more efficiently across distances than analog lines Because many telephone networks are moving over to digital interfaces
What is logic for ground in digital electronics?
In some types of electronic design you may have Digital circuits also called Logic Circuits and Analog circuits. Each circuit may have separate power and ground lines. So you may see the notation on a schematic for Logic Ground or Analog ground.
What is the diff between analog ground and digital ground?
Typically digital circuits will pump a lot of fast transient currents into the ground. Since real grounds have resistance and inductance, this will produce a drop between the ground of the digital circuits and the power supply ground. This is the so called "ground bounce". If an analog circuit ground shares ground path between the digital ground and the power supply ground, it will see this voltage drop. Depending on the common mode rejection of the analog circuit in question and the frequency components in the "ground bounce" this may or my not be an issue. If it's an issue, the easy solution is to connect the analog ground directly to the power supply ground without sharing any of the path from digital ground to main power supply ground. This way the current spike induced drops in the digital ground don't show up in the analog ground. A good example would be ADC grounding for the digital and analog portions of the ADC chip.
What are the applications of Time Division Multiplexing technique?
All signal multiplexing techniques were invented to permit a single physical communication channel to carry multiple different signals. This reduces the investment costs in physical communication channels: e.g. long distance telegraph lines, long distance telephone lines, microwave links, orbiting communication satellites, fiber optic cable. Time Division Multiplexing can be implemented using either analog or digital signaling means.
What is a device that translates computer signals to analog signals suitable for sending across phone lines?
A modem. Short for MOdulate-DEModulate.
Can fiber optical lines be analog or digital?
It can be either or depending on the circuit, here's a link that will help you more: http://communication.howstuffworks.com/fiber-optic-communications/fiber-optic.htm
How does modern work for computer?
you mean modem? MO-DEM MOdulation / DEModulation. It turns your digital signal into analog, so it can go thru the phone lines to your isp, and then from the phone lines to their server, it converts the analog signal back into digital.
Whatis the function of modem?
MOdulate/DEModulate. It converts digital computer signals into analog ones for transmission over analog telephone lines, and then converts the signal back into digital on the other end.
Why is a modem needed for analog telephone lines?
A modem (which stands for Modulator-Demodulator) converts digital data from the computer to analog data compatible with the telephone system. The analog signal is converted back into digital data on the other end of the call.
What kind of lines consist of two digital channels over the same copper wire used by regular analog telephones?
Integrated Services Digital Network (ISDN) lines
Why is it necessary to digitize voice signals?
To minimize the distortion of analog signals during transmission Because digital lines transmit signals more efficiently across distances than analog lines Because many telephone networks are moving over to digital interfaces
What are the differences between a mounted digital kitchen scale and a standard analog kitchen scale?
The main difference between these scales it that the digital will give a more accurate and easier to read reading than figuring it out with the lines between the numbers the analog scale. However, the digital scale requires and battery and the analog does not.
What are five types of digital dedicated lines?
Hi, Hello, Sup, Yo, Hey
What is an analog phone line?
It would probably be easiest to give you some examples of an analog line. Usually the phone you have in your house is an analog line. Another example would be a typical fax line. Another example would be the typical line that your computer would use for a dial up connection. Perhaps the debit machine would use an analog line, but some might use a computer connection also. I just read on one web site that if your phone complies with "complies with part 68, FCC Rules" and a Ringer Equivalence Number (REN), then the phone and the line are analog. So generally if the phone in your house will work on that line then it is analog, if it won't then likely it is digital. Digital is a line where the voice has been converted to 1's and 0's and the reconverted back to voice at the other end of the line. Digital lines are generally use in business's, although a business might have either digital or analog lines. Notice on this page http:/www.telephonemagic.com/meridian_centrex_phones.htm although all the phones are considered business phones, the digital phones are on the left and and the analog phones are on the right. Then again your cordless phone in your house might be digital from the base to the handset, but still the line is analog.
What hardware is needed to convert the digital signal of the computer to signals that can be transmitted through telephone lines?
modemmo-dem =MOdulatorDEModulator
What Technology used to modify analog signals to make them suitable for carrying data over a communication path?
MODEM (Modulator - Demodulator)modulates Digitals signals to Analog to send over Telephone lines and Demodulates Analog signals in Digital Signals.
What device changes digital computer data into analog data that can be sent over phone lines?
A modem performs this function. A modem converts digital information to analog information to transmit a signal over phone lines. The process of converting this signal in this manner is modulation. They also convert analog information back to digital information to receive data. This is called demodulation. The name modem is a combination of the words modulator-demodulator.
