What are regenerative repeaters used for?

A regenerative repeater amplifies and reconstructs such a badly distorted digital signal and develops a nearly perfect replica of the original at its output. Regenerative repeaters are an essential key to digital transmission in that we could say that the “noise stops at the repeater.”

What is the purpose of using regenerative repeaters in long distance communication?

In telecommunications, a repeater is an electronic device that receives a signal and retransmits it. Repeaters are used to extend transmissions so that the signal can cover longer distances or be received on the other side of an obstruction.

What are regenerative repeaters?

regenerative repeater: A repeater, designed for digital transmission, in which digital signals are amplified, reshaped, retimed, and retransmitted.

What are repeaters in digital communication?

1) In digital communication systems, a repeater is a device that receives a digital signal on an electromagnetic or optical transmission medium and regenerates the signal along the next leg of the medium.

Which of the following is not a function of the regenerative repeater?

Which of the following is not a drawback of regenerative repeater? Explanation: The regenerative repeaters are useful in long haul applications. However, such devices increase the cost and complexity of the optical communication system. It act as a bottleneck by restricting the system operational bandwidth.

What is the use of PN sequence in digital communication?

Peudo-Noise sequences or (PN) are randomized spreading sequences , that resembles noise signals , used in many wireless communications standards [ such as : CDMA-2000 and UMTS] , to spread the transmitted data sequences over longer sequences of 0s and 1s , which makes it more powerful against fading and noise effect .

What is a repeater and how does it work?

How does it work? A repeater receives the radio signal on one frequency and simultaneously transmits the same signal on another frequency. Typically, a repeater is placed in a location where it can have a virtual line of sight to all radios in the system.

What are the functions of non regenerative repeaters?

What are the functions of non-regenerative repeaters? Explanation: A non regenerative repeaters can be used with many different modulation formats. It only amplifies and re transmits the message received.

Which of the following is not a function of regenerative repeater?

How do amplifiers differ from repeaters?

The main difference between repeater and amplifier is that repeater is used as a regenerate the signal and amplifier just increases the amplitude of the signal.

Does repeaters operate only at the physical layer?

Repeaters: A repeater is a device that operates only in the physical layer. Signals that carry information within a network can travel a fixed distance before attenuation endangers the integrity of the data. A repeater receives a signal and, before it becomes too weak or corrupted, regenerates the original bit pattern.

What is a regenerative repeater and how does it work?

A regenerative repeater amplifies and reconstructs such a badly distorted digital signal and develops a nearly perfect replica of the original at its output. Regenerative repeaters are an essential key to digital transmission in that we could say that the “noise stops at the repeater.”

Can I use a normal comparator to regenerate a digital signal?

Using a normal comparator to regenerate the digital signal, there would be errors. If the reference voltage is the grey centre line the noise is large enough cross the reference line. This causes the errors.

What are the advantages of digital signals over analog signals?

Digital signals can be saved and retrieved more conveniently than analog signals. Many of the digital circuits have almost common encoding techniques and hence similar devices can be used for a number of purposes. The capacity of the channel is effectively utilized by digital signals.

What are the advantages of on-board regeneration?

Introduction of on-board regeneration alleviates the conflict between enhanced traffic capacity and moderate system cost by reducing the requirements of the radio front-ends, by simplifying the ground station digital equipment and the satellite communication payload in TDMA and Satellite-Switched-TDMA systems.
