What type cable has the highest resistance to noise and carry a signal the longest distance?
The type of cable that enables the longest transmission with the lowest loss is called Goubau line, or G-line, for short. This line has far less loss than either coaxial cable or parallel line (twinlead). By using conical shaped "launchers", G-line creates a type of waveguide.
What else can I help you with?
What are the steps involved in finding the signal gain for a common-emitter BJT amplifier?
The signal gain of a CE BJT amplifier is hFe or collector resistance divided by emitter resistance, whichever is less.
What is the distance up to which the clap switch receives sound signal?
It's not the distance, it's the decibel.
What is the gradual loss of signal strength?
The gradual loss of signal strength, often referred to as signal attenuation, occurs as a signal travels through a medium, such as air or a cable. Factors contributing to this loss include distance, interference, and the properties of the transmission medium, such as resistance or absorption. This phenomenon can affect various forms of communication, including radio, television, and internet signals, ultimately leading to degraded performance or quality. Effective measures, like amplifiers or repeaters, can be used to mitigate signal attenuation.
Can you have a radio signal underground?
Yes, you can however the distance that a signal may be travel depends on the power and frequency of the signal. For signals at the same power a lower frequency signal will travel further.
Why FM is used for short distance communication?
Frequency Modulation (FM) is used for short-distance communication primarily because it offers improved sound quality and resistance to noise and interference compared to amplitude modulation (AM). Its ability to maintain signal integrity over shorter distances makes it ideal for applications like local radio broadcasts, two-way radios, and personal communication devices. Additionally, FM's bandwidth allows for a more robust signal, facilitating clearer audio transmission in environments with potential signal disruption.
What signal has the longest wavelength?
The signal with the longest wavelength is radio waves. They have wavelengths ranging from meters to kilometers.
Is a measure of the highest frequency of signal a multimode fiber can support over a specific distance and is measured in MHz-km?
Modal bandwidth
Effects of the electric resistance on a signal?
Weak signal depending upon the type of signal.
What limited the distance you could transmit with lectrical telegraph before using a repeater?
The distance of electrical telegraph transmission was primarily limited by signal degradation due to resistance in the wire, which caused attenuation of the electrical signal over long distances. Additionally, factors like capacitance and inductance in the telegraph lines would further diminish signal clarity. Without repeaters to boost the signal, these limitations restricted effective communication to relatively short ranges. Repeaters allowed the signal to be amplified, enabling longer distances to be covered reliably.
What effect will increasing the required transmission distance have on transmitting the signal clearly?
Increasing the required transmission distance of a signal will have a negative effect on the clearness of the signal. As the source is moved farther away from the receiver, a weaker signal will be present.
What are the steps involved in finding the signal gain for a common-emitter BJT amplifier?
The signal gain of a CE BJT amplifier is hFe or collector resistance divided by emitter resistance, whichever is less.
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 is loss of signal over distance called?
Attenuation
Why the power of the spreading signal is reduced with respect to the original digital signal?
aatenuation due to long distance
What is the distance up to which the clap switch receives sound signal?
It's not the distance, it's the decibel.
Can you have a radio signal underground?
Yes, you can however the distance that a signal may be travel depends on the power and frequency of the signal. For signals at the same power a lower frequency signal will travel further.
What is the explanation for the features of repeaters?
Signal strength diminishes over distance. A repeater boosts signal strength and passes it on.
