Light.
depends on the purpose of the device
They used the transmitted to transmit the signals from the island they were stuck in. Transmitter here is an electronic instrument.
Analog signals are transmitted as electrical waves.
Analog signals are transmitted as electrical waves.
Vision takes place in the eye's retina, where light is converted into electrical signals. These signals are then transmitted to the brain via the optic nerve, where they are processed and interpreted to form visual perceptions.
This is due to electronic signals are transmitted between brain and other parts of the body; the ever fastest communication.
Once sound energy enters the mouthpiece of a telephone, it is converted into electrical signals by a microphone. These electrical signals are then transmitted through the telephone wire to the earpiece at the other end, where they are converted back into sound waves that can be heard by the listener.
Sound waves enter the microphone and cause a diaphragm to vibrate. These vibrations are converted into electrical signals which are then amplified by the microphone. The electrical signals can then be transmitted to a recording device or sound system for playback.
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)
An electronic device converts the sound waves into a digital signal/code that is then transported by microwaves or radiowaves, until it reaches another device that converts that code back into a soundwave.
Voice signals are converted to digital data, transmitted as light pulses through fiber optic cables using lasers, then converted back to voice signals at the receiving end by using photodetectors. This process allows for transmitting voice communication across long distances quickly and efficiently.
your brain sends them electric signals to the leg and the leg transfers the signals through fiberoptic cables. however it may take your leg longer to respond than a normal leg.
