What is the explanation for the features of repeaters?
Signal strength diminishes over distance. A repeater boosts signal strength and passes it on.
What are three imporatant characteristics of a periodic signal?
same signal pattern over time, how much time does it take to transmit a cycle
Why is digital technology preferred to analog technology in communications technology?
Why digital communications and what its advantages over analog communication ,first you have to know what is the difference between analog signal and digital signal. Analog signal analog signal is continuous time signal i.e. it has a value at any moment of time and it has infinite number of valus , such as dinusoidal signal ,you can substitute X with any value and you will have an value in Y in the follwing sin relation Y=sin(X). 1-Noise and destortion immunity:-when analog signal is transmitted in free space for long distances it will be distorted and no an ideal recovery done in receiver to recover the exact signal which transmitted ,but in digital communication digital signal consist of 2 levels only zero or one (not like the analog one , it has infinite numbers of values or levels at each period of time),so digital signal can be recovered easily and excactly like transmitted one. Hint : Device that used to pattially recover the analog signal after a certain distance is called repeater ,from its name it receives transmitted analog signal and filter it and amplify it and transmitt it),but in digital transmission it is different ,the device used for recovering digital signal which transmitted from acertain distance is called regenerative repeaters ,it receives transmitted digital signal and recover it to regenrate a new exact signal like received one then retransmitt it for further distance. 2-More privacy and security due to encryption. 3-Error detection techniques can be used and correction as well. 4-Easy for processing and applying multiplexing techniques. 5-Low cost. 6-Transmission rate can be changed easily. 7-Digital hardware implementation is flexible and permits the use of micrprocessors, digital switching elements and layer scale.

How is hydraulic grade line effected by increased distance to the water pump station?
The hydraulic grade line will drop over distance due to friction loss in the pipe. For example if you had 10m of 100mm pipe and the water was flowing at 8.71 liters per second at a velocity of 1.185 meters per second you would lose 1.317 kilo pascals of pressure.
What is modulization?
Any device or circuit by means of which a desired signal is impressed upon a higher-frequency periodic wave known as a carrier. The process is called modulation. The modulator may vary the amplitude, frequency, or phase of the carrier.
What is the attenuation loss and how it related to distance?
Attenuation loss refers to the reduction in signal strength or power as it travels through a medium, such as a cable or air. It is directly related to distance, meaning the further the signal travels, the greater the attenuation loss. This is because signal energy is dispersed and absorbed over distance, leading to a decrease in signal strength.
What are the differences between low attenuation and high attenuation in terms of signal strength in a communication system?
Low attenuation refers to a situation where the signal strength remains strong over long distances, resulting in minimal loss of signal quality. High attenuation, on the other hand, indicates a significant decrease in signal strength over distance, leading to potential loss of signal quality.
What is attenuation in decibels?
The degeneration of a signal over a distance on a network cable is called attenuation. It does not have any relation with decibels. The strength of signal just gets reduced.
What is the primary cause of signal loss in satellite communication?
Free Space Loss is the primary source of signal loss in satellites. As the signal propagates through the atmosphere it disperses. With normal terrestrial antennas, the distance is so short that this is rarely an issue. However, the great distances that satellites must communicate over make this a major problem for global space-based communication.
Is it true that there was signal lost for the wireless cellphones?
There is signal loss, over distance for any wireless (Radio) system. The cellular system gets over this problem, by using only short ranges between cells. A cell phone swaps signal, from one cell to another and changes frequency automatically.
How does noise dissipation over distance affect the performance of communication systems?
Noise dissipation over distance can weaken the signal strength in communication systems, leading to potential errors or loss of information. This can result in decreased performance and reliability of the communication system.
How can I ensure a stable and high-speed internet connection over a distance of 1000ft using Cat6 cables?
To ensure a stable and high-speed internet connection over a distance of 1000ft using Cat6 cables, you can use signal boosters or repeaters to amplify the signal strength and reduce interference. Additionally, make sure to properly terminate and shield the cables to minimize signal loss and maintain data integrity.
What is the explanation for the features of repeaters?
Signal strength diminishes over distance. A repeater boosts signal strength and passes it on.
What is attenuation network?
Attenuation is a measure of how much loss a signal experiences when it travels down a communication medium( loss as heat, absorbed by communication medium).It is mesured in decibels Attenuation is a term that refers to any reduction in the strength of a signal, when transmitting over a long dinstance. Attenuation occurs with any type of signal, whether digital or analog. It is also called loss of signals, The extent of attenuation is usually expressed in units called decibels (dBs).
Does a router work to increase your wifi signal?
A router distributes a signal that is as big as it is set to, it will not increase distance over time.
How do you get high resolution video from a computer to a high definition television over an extended distance without degrading the signal?
S-Video cable can be run up to 75 ft with almost no loss in resolution.
Where does attenuation occur?
Attenuation typically occurs in processes involving the weakening or reduction of a signal's strength, intensity, or energy. In communication systems, attenuation can happen in transmission lines, optical fibers, or wireless channels, leading to signal loss or degradation over distance. It is essential to account for attenuation to maintain signal quality and integrity in various applications.
