How is data retrieved from the telephone?
how is data retrieved from the telephone? the transmitter converts the sound waves to electrical signals which are sent through the telephone network to the receiving phone. the receiving telephone converts the signals into audible sound in the receiver.
What describes the combination of voice such as telephone video and data signals sent over the same network?
Convergence
How can two computers communicate over public telephone network?
Two computers can communicate over a public telephone network by using modems to convert digital signals into analog signals suitable for transmission over telephone lines. Each computer connects to a modem, which dials the phone number of the other computer's modem. Once a connection is established, the modems facilitate the exchange of data by encoding and decoding the signals back into digital form. This allows the computers to send and receive information effectively over the network.
How are vibrations changed into electrical signals by the telephone?
In a telephone, sound vibrations from a speaker's voice cause a diaphragm in the microphone to vibrate. These vibrations create variations in air pressure, which are then converted into corresponding electrical signals through electromagnetic induction or capacitance. The electrical signals are then transmitted through the telephone network and can be reconverted into sound at the receiving end by a speaker. This process allows for the transmission of audio information over distances.
What travels in a telephone?
Signals.
What converts analogue signals to digital signals for transmission over telephone lines?
Actually you have this backwards, the telephone lines can only carry analogue signals (voice band, 20Hz to 3KHz) not digital signals.The device that converts digital signals to analogue signals for transmission over telephone lines is called a phone MoDem(this stands for phone modulator demodulator). At the opposite end of the line it of course converts the telephone analogue signals back to digital signals.
What are binary telephone signals?
Telephone signals that are made from the binary code, which originates from the base two numbers 0 and 1
How far can cellular telephone signals travel?
Cellular telephone signals can travel up to 22 miles.
What part of the telephone network depends on analog signals?
In traditional telephone networks, the local loop, which connects individual homes and businesses to the central office, primarily relies on analog signals. These analog signals transmit voice communications over copper wire. While much of the backbone and long-distance transmission has shifted to digital formats, the last mile connection often still uses analog technology, especially in legacy systems. However, many newer systems are transitioning to digital methods for improved efficiency and quality.
How is DSL able to carry telephone and data signals at the same time?
Both telephone and data signals can be received at the same time by use of a microfilter. This device increases the data-carrying capacity of the line without disturbing the telephone signals.
How is LAN communication different from telephone communication?
LAN stands for local area network, and has nothing to do with telephone communications. LAN has 2 purposes:1.allows multiple computers to use the same internet connection,2.allows local computers to talk to each other(exmaple: sending a file from your computer to you're sister's computer)A telephone uses analog signals, a LAN uses digital signals.
What three aspects of the electrical signals carried over the telephone network can be varied by modems to encode data in the signal?
Modems can vary the amplitude, frequency, and phase of the electrical signals transmitted over the telephone network to encode data. Amplitude modulation changes the strength of the signal to represent different data values, frequency modulation alters the signal's frequency for encoding, and phase modulation shifts the phase of the signal to convey information. By manipulating these aspects, modems effectively translate digital data into a format suitable for transmission over analog telephone lines.
