What else can I help you with?
Are the modem and the codec functional inverses ie could an inverted modem?
No, the modem and codec are not exactly the functional inverse of each other. teh modem converts the digital data to analog signal by teh modulating part of it. teh demodulating part of the modem can be used to covert teh ANALOG SIGNAL to digital data....but this analog signal will be modulated analog signal. the coding part of teh codec convert teh analog signals to teh digital signal .these analog signals are pure analog signals. Hence teh codec and modem may seem as functional inverses but do not work as so due to teh fact dat the demodulating part of the modem used only the modulated analog signal and cannot process the pure analog signals .
Which piece of network hardware converts analog signals to digital and digital signals to analog?
a modem
Who is MODEM?
Modem is a what not a who. A computer modem is a device that uses an analog carrier signal to encode digital information. The modem is how you connect to dial up Internet.
How modem is used for data transmission?
fax
Can you use an Analog Modem on a Digital Phone Line?
Y
How do computers input analog signals?
due to the use of MODEM
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 is the difference between a modem and a codec?
* Codec is for coding analog data into digital form and decoding it back. The digital data coded by Codec are samples of analog waves. * Modem is for modulating digital data into analog form and demodulating it back. The analog symbols carry digital data.
What piece of equipment is used to translate digital signals into analog format for delivery across analog links?
modem
What is a modem's function?
To transceive digital data over analog media.
What is modem and how does it relate to Dial-Up connection?
"MODEM" stands for "modulate/demodulate" The modem changes digital signals into analog tones that can be sent across a telephone wire.
Why do you use modem?
modem means modulator demodulator. it converts digital signal to analog signal. it is use to transmit computer signal (digital signal) over the telephone line to communicate to other computers. modem converts the computer digital signal into frequency (analog signal) so that it can transmit over the telephone line and at the receiving end the modem converts the analog signal back to digital for the receiving computer to understand it.
