It is true. The book says "The maximum distance a signal can travel and still be interpreted accurately is equal to a segment's maximum length. Beyond this length, data loss is apt to occur."
true
The quality of a signal is a measure of how much the signal has changed during transmission. A high quality signal has changed very little. A low quality signal has other information in it which was not there in the original signal. The additional unwanted information is called noise.
The distance between two crests of water is the "wavelength."WavelengthIs a one complete wave length(wave lenght)That would be the wavelength.wavelengthIn a wave, the distance from crest to crest is commonly called a wavelength.wavelengthThe distance between two corresponding crests on any type of wave is called a wavelength.That is what is considered the wavelength. Same thing with the troughs.wavelengthThe frequency of the wavelenght, or the Hertz, is the distance between two crests.ans2. wavelength is sufficient.The frequency (Hertz) will depend on the speed of the signal in that medium. Just ignore "Hertz" in the first sentence.wavelength. Which affects frequency.In sound it determines pitch. In visible light it determines color.In waves, the distance is the period. The frequency of the wave is equal to the inverse of the period.Wavelength.wavelengthdistance between two adjacent crests is called as WAVELENGTH.......Distance between two crests is the wavelength of a wave.wavelength (distance between two crests or troughs) !Wavelength.wavelengthThe distance between two consecutive crests or troughs of a transverse wave is called the wavelength.The distance between consecutive crests or troughs on a wave is called as wavelength.Wavelength
Usually deals with hypersonic wavelengths, kinda like how bats see, and they see how long it takes to hear the signal back. Then they divide the time by 2, since the time given was the time down and back up, then they find out the speed of the hypersonic wavelength, and plug it in to the sound.
The pitch period of a signal is the fundamental period of the signal, or in other words, the time interval on which the signal repeats itself. The pitch frequency is the inverse of the pitch period, which is the fundamental frequency of the signal.
One if by land and two if by sea is the signal you shall set for me! The signal's yellow light was more green than red, officer! Semaphore utilizes signal flags.
True
The maximum length of a cat 5 e cable with out a repeater is 100meters
The BNC (Bayonet Neill Concelman) connectoris a very common type of RF connector used for terminating coaxial cable.There is no predetemined maximum length for the coax cable. The maximum length of cable is going to be governed by determining the input signal level, the minimum output signal level, and the signal loss based on the length of the cable between the input and minimum output.
If you exceed the maximum distance of any cable, the resulting transmissions will be subject to attenuation. The longer the distance, the weaker the signal becomes, until it becomes weak enough to be considered noise, and no longer considered data.
So that it doesn't lose the signal completely before reaching the repeater.
So that it doesn't lose the signal completely before reaching the repeater.
higher frequencies attenuate more the further distance they travel.
white is the colour which we can see from the maximum distance and red is a alert signal or danger signal and has good reflections also.
It uses the maximum power available to the transmitter and makes the signal more readable at a greater distance.
The maximum distance an IrDA device can trasmit is 1 meter. The effective range between two IrDA devices is 2 meters.
The signal can only be sent so far before becoming distorted
radio signal bents around the curvature of earth and hence travel longer distance than the line of sight signal. At ultra high frequencies signal follows the line of sight path and hence maximum communication distance is limited due to curvature of earth for given height of transmitting and receiving antenna
