Why FDM is for analog signals and TDM is for digital signals?
FDM stnds for frequency division multiplexing and it is used only in case of analog signals because analog signals are continuous in nature and the signal have frequency. TDM-stands for time division multiplexing and it is used only in case of digital signals because digital signals are discrete in nature and are in the form of 0 and 1s. and are time dependent.
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.
Many network hubs incorporate repeaters or amplifiers to regenerate signals so that attenuation of the signal does not occur?
As a rule a hub does not contain a repeater. Amplifiers would be used in analog communication, not digital communication. Attenuation is a process that occurs all the time in networks; you would place a repeater in an area where the attenuation would cause the signal to degrade to the point where it wouldn't be usable. You would want the repeater to be placed before that point.
What retransmits radio signals in a new direction?
repeater
What device is used to convertanalog signals to digital?
ADC analog digital converter
What converts a binary signal to analog?
an encoder is used to convert the binary signals into analog signals. the binary signals are fed to encoder section. then these signals are get converted into its equivalent analog signals. Binary DAC.
Name the device that is used to regenerate data and voice signals?
Repeater
7 What term is used to describe the transformation of analog signals into digital signals?
Transforming analog signals to digital is known simply as analog to digital conversion, sometimes shortened to A-D conversion.
How are analog signals received?
Analog signals can be received using an analog receiver.
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.
How are analog signals transmitted-?
Analog signals are transmitted as electrical waves.

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 piece of equipment is used to translate digital signals into analog format for delivery across analog links?
modem
What is analog simulation?
Analog system simulation is more sensitive to the changes in the parameters compared to the digital system. This is because of the continuous nature of the analog signals, unlike the discreet nature of the digital signals. Digital systems have gates which can not be used in Analog system.
