What else can I help you with?
What is a PSTN interface?
Analog connection to the Public Switched Telephone Network.
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 an analog network?
a network that is analog.
What is Analog carrier system used in telephony?
Analog Carrier System is a transmission system that uses repeaters that compensate for analog medium impairments, and produce output signals that are linear-scaled versions of input signals. Analog carrier systems can carry speech, data, video and supervisory signals although they are best suited for speech signals.
Whats the difference between analog and digital signal?
Analog signals are continuous while digital signals are discrete
What portion of the telephone network still depends on analog signals?
Analog data transmissions occurs every time you log onto the internet using your pc, your modem, and your telephone line.
What is the transfer of digital or analog data using digital or analog signals?
The transfer of digital or analog data using digital or analog signals refers to the process of transmitting information from one device to another, either through digital signals or analog signals. Digital signals are electronic signals that represent binary data, while analog signals are continuous signals that represent continuous data. The method of transfer depends on the type of data being transmitted and the technology being used for the transfer. For example, digital data can be transferred using digital signals through a computer network, while analog data can be transferred using analog signals through a telephone line. Regardless of the method used, the goal of the transfer is to accurately transmit the information from one location to another.
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.
Which piece of network hardware converts analog signals to digital and digital signals to analog?
a modem
What is a PSTN interface?
Analog connection to the Public Switched Telephone Network.
Does Nearly the entire telephone network today uses analog technology?
No, most of the landline telephone network and almost the entire mobile phone network use digital technology.
What is meant by modulation and demodulation?
The full form of Modem is Modulator-demodulator. Modulation is process of converting the digital computer signals to analog telephone signals. Demodulation is the opposite conversion, analog to digital.
What does the public switch telephone network use?
Analog switches Fiber optic cables
How are analog signals received?
Analog signals can be received using an analog receiver.
