What contains circuitry that converts the data-carrying signals from your computer to signals that can travel over various communications channels?
modem
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.
Does a digital signal travel farther than an analog signal?
You need to make a distinction between analog and digital signals, and analog and digital data. Digital data can be sent on an analog signal by using a modem. Digital data sent on a digital signal is done over a wire using voltage pulses at two or more levels. Digital signals can't travel very far without amplifiers, but analog signals can cover huge distances, such as with satellite communications and even communications with deep space probes.
How did the steamboat change the peoples lives at the time?
It help travel
Is optical fiber unidirectional?
The optical fiber can be used both as unidirectional and bidirectional. The main application of optical fiber is in long-distance links, so there exists no need to employ them as unidirectional. For each direction different wavelengths are used to modulat the signals. At the same time many bidirectional signals can travel through the same optical fiber.
How do you FM signals travel?
They travel in a back and forth motion
How far can cellular telephone signals travel?
Cellular telephone signals can travel up to 22 miles.
Why would a lack of neurotransmitters change the function of the brain?
signals travel from neuron to neuron through neurotranmitters
How do signals from the hypothalamus reach the pituitary gland?
Signals heading to the anterior pituitary travel through the hypophyseal portal vein. Signals heading to the posterior pituitary travel through the pituitary stalk or infindibulum.
What kinds of signals travel without air?
people who have powers
What kind of signals can travel without air?
people who have powers
What is the name of the cells in which nerve signals travel through?
Neurones
Why does television signals travel through a vacuum?
television signals are communication signals, which can either be radio or microwave signals. These are both part of the electromagnetic spectrum. In the spectrum all the different signal types have some similar properties, including being able to travel through a vacuum, usually because they have a strong enough frequency and wavelength, and they don't need to travel in particles but waves :)
What contains circuitry that converts the data-carrying signals from your computer to signals that can travel over various communications channels?
modem
Can radio signal travel through salt water?
Radio signals can travel through salt water.
Electric signals whose values change smoothly over time are called?
Repetitive signals are referred to as periodic signals, while signals that constantly change are known as non-periodic signals. A still picture is analogous to a periodic signal, while a movie is analogous to a non-periodic signal. Synchronous and Asynchronous Signals.
A form of transmission that allows multiple signals to travel simultaneously over one medium is known as?
A form of transmission that allows multiple signals to travel simultaneously over one medium is known as multiplexing
