What is the DSL port called?
DSL stands for Digital Subscriber Line. Which basically means a telephone line, that has a signal superimosed on it, by a service provider, to enable a broadband internet connection.
What is different about the method used to boost digital signal strength compared to the method used to boost analog signal strength?
A digital signal requires a repeater, which retransmits the signal in its original form, and an analog signal requires an amplifier, which increases the strength of both the signal and the noise it has accumulated.
A line has a signal-to-noise ratio of 1000 and a bandwidth of 4000 KHz what is the maximum data rate supported by this line?
The Formula is C=B log_2 (1+SNR) = 4000 log_2 (1+1000) = 4000 x 9.9672 = 39868.8.
What are Modems used for in Internet?
Basically, modem is used to connect the analog world to the digital world. In other words, you can say it is the device that is used to convert the analog signal to digital signal. For eg. the modem connected with a computer is usually converts the analog signal that comes through the wire to the digital bit bcoz computer can only understands the digital signal...
Propagation of operation in object modeling?
Propagation means triggering ie something which fires automatically. Thepropogation of operation is applied with aggregation, if some operation is applied with the high level aggrigate the same operation will be performed with all lower aggregates. For example in aggregation between document and paragraph if we will perform an operation copy with document it will automatically applied with paragraph also. This propagation of operation. kailash
Why ground wave propagation is not suitable for higher frequency?
Ground wave propagation becomes less suitable for higher frequencies because the signal tends to be absorbed by the ground more efficiently, resulting in shorter range and reduced coverage. At higher frequencies, signals are more likely to be affected by atmospheric conditions and obstacles, making ground wave propagation less reliable compared to other propagation methods like line-of-sight or ionospheric propagation.
What is isotropic propagation?
Isotropic propagation refers to transmission when the electromagnetic radiation radiate uniformly in all direction in the shape of "sphere" (assuming free-space physical model). Such radio propagation is also known as "omni-directional".
What are the secondary constant of transmission line?
The secondary constants of a transmission line are the surge impedance, propagation constant, attenuation constant, and phase constant. These constants determine the behavior of signals traveling through the transmission line and are important for analyzing the performance of the line in terms of signal integrity and power transmission.
What tool can you use to see what trees are in the way for satellite signal?
Obviously one tool is your eyes. You can look at the area line of site to see if any trees may be in the way of the signal.
What are the uses of rectilinear propagation of light?
Rectilinear propagation of light refers to light traveling in a straight line. This property is utilized in various applications, such as in optical communication systems to ensure minimal signal loss, in creating sharp images in photography, and in designing optical instruments like microscopes and telescopes for accurate visualization.
What is fading in telecommunications?
In wireless communications, fading is deviation or the attenuation that a carrier-modulated telecommunication signal experiences over certain propagation media.
What is the unit vector n that points in the direction of propagation?
The unit vector n that points in the direction of propagation is a vector with a magnitude of 1 that indicates the direction in which a wave or signal is moving.
What does salts serve in cells?
Osmotic pressure. Trans-membrane voltage potential. Rapid signal propagation.
What is the form of wave in which the particles vibrate parallel to the line of propagation?
Longitudinal.
What is a signal site criterion?
Selecting a signaling site and putting your signal in a suitable location is critical. A signaling site is defined as any site, based on your situation that enhances signaling efforts and the likelihood for the signal to be detected by friendly forces. What is a signaling site criterion?
What is skywave propagation?
Skywave propagation is a method of radio signal transmission where signals are reflected off the ionosphere back to Earth, allowing long-distance communication without the need for line-of-sight between transmitter and receiver. This phenomenon is commonly used for long-distance shortwave radio communication and can be influenced by factors such as solar activity and atmospheric conditions.
What are the main signal propagation?
Solar activity (sunspots in particular), atmospheric conditions, distance, and geography between transmitters and receivers.
