Repeater
A transducer.
The networking device that receives a digital signal transmission and regenerates the signal for the next leg of the medium is called a repeater. Repeaters amplify or regenerate the signal to extend the transmission distance, ensuring that the signal maintains its integrity over longer distances. They are commonly used in various types of networks to overcome attenuation and maintain communication quality.
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
There is a device called a digital to analog converter (DAC).
hub
The network device that regenerates data signals without segmenting the network is a repeater. Repeaters are used to prevent attenuation of signals.
a passive hub does not regenerate the signal received only let it pass
An analog-to-digital converter is a device which converts an infinite resolution analog signal to a finite resolution digital signal.
When any digital signal is transmitted over a pair of wires, it degrades in amplitude. Regenerative repeaters receives the incoming signal, extracts the clock, then regenerates the original signal as a clean digital square wave as if it was the original signal transmitted from the source. Thus the name repeater.
An analog-to-digital converter is a device which converts an infinite resolution analog signal to a finite resolution digital signal.
This is an electronic device which converts electrical signal into a digital signal.
