What are strands of glass tha transmit digital data by pulses?
Fiber optic cables transmit digital signals as pulses of light.
What are signals composed of pulses of precise positive voltages and zero voltages?
Digital
How are digital signals in radio broadcast converted to analog signals inside digital transmission equipment before sending the signals to the antenna for transmission?
The digital signals is not converted BACK to analog! it is transmitted in digital form and the receiver is converting it back to analog to drive the speakers. The signal from the microphone is converted from analog to digital with an A/D converter chip, digital signals consist of pulses of different lengths that is switching the transmitter on and off in about the same way as the old Morse code transmissions but at a much higher rate (millions of times higher)
What is a digital signal?
they are non continuous signals that consist of pulses or digits with dicrete levels or values (usually with value 0 or 1). In digital transmission, the singlas are converted to bindary code.
State the energy changes involved when information is communicated from one computer to another through a fiber optic network?
The fibre optic cable transmits light pulses, so you need at the sending end a device to turn electrical pulses from the computer into light pulses, and at the receiving end one which does the reverse.
What are composite signals why you needed?
In case of TV broad casting, the Video Signal is not transmitted alone, but it accompanied by a number of other signals or pulses, which help the exact reproduction of the picture at the receiving end. These pulses include Blanking Pulses, Synchronizing pulses and Equalizing pulses. A combination of Picture signal and other Controlling signal or pulses is called Composite Signal. Thus Composite Video Signal may consist of Following Parts.Picture information (Data)Blanking Pulses (Delay Pulses)Vertical and Horizontal Synchronizing Pulses (controlling Pulses)Generally,A Combination of Data and Other Controlling Signal is Called Composite Signal .
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.
Advantage of digital signal?
Higher immunity to noise, storage of digital signal is cheap and easy, its representation is only using two levels as opposed to infinite levels for analog
What is the name given to the electrical signals in your body?
pulses
What do lasers convert electrical signals into pulses of?
coherent light
Which types of signals are carried over a DSL cable?
DSL is carried over a phone line. Yet it caries digital signals. the telephone company has to limit the bandwidth of the analog voice on the lines. So DSL is able to use the unused portion of the bandwidth to transmit digital data. hope that helps -------------------------------------------------------------------------------------------------------- According to Cisco : Network devices link together using a variety of connections: * Copper cabling - Uses electrical signals to transmit data between devices * Fiber-optic cabling - Uses glass or plastic wire, also called fiber, to carry information as light pulses * Wireless connection - Uses radio signals, infrared technology (laser), or satellite transmissions. so your answer would be electrical signals.
What are tiny pulses of electricity that move along a nerve fiber?
Nerve signals Thats what my crossword was.
