telephone
What part of a microphone converts sound waves into an electrical signal?
The diaphragm
What is meant by attenuation in Optical Fiber Communication?
When an optical signal of a given wavelength travels in the fiber it looses power. The amount of loss of power per Km length of fiber is called its attenuation. A=10*LOG10(POUT/PIN) dB/Km Where POuT is optical power after 1 Km PIN is th epower launched in the Fiber.
How are electronic volumes measured?
electronic volume can be measured by using transducer transducer is a device which convert non electrical signal to electrical signal. First you need a microphone which is a transducer after that apply the sound vibration on this microphone it will produce a voltage the voltage is directly proportional to applied sound volume level. it measure in decibel.
Whats the main difference between small signal amplifier and large signal amplifier?
1.Small signal amplifier can be designed easily using s parameter while large signal amplifier not.
How camera tube in TV converts optical signal into electrical signal?
hi
How you can convert an electrical signal into an optical signal?
electrical signal can be converted to an optical sigal by using a LED or SOA(semiconductor optical amplifier). LED is the cheaper option but have the drawback of larger linewidth. Typically used for LAN (local area network). SOA produces an optical signal mostly by direct modulation tecnique .
Can you propagate optical signal over electrical network?
only over fiber
Difference between active and passive optical component?
Fiber optic couplers can be either active or passive devices. The difference between active and passive couplers is that a passive coupler redistributes the optical signal without optical-to-electrical conversion. Active couplers are electronic devices that split or combine the signal electrically and use fiber optic detectors and sources for input and output.
What is meant by atenuation in fiber optics?
Attenuation in fiber means 'loss of optical power' suffered by the optical signal in fiber itself.
What is the difference between primary and secondary transducers?
the difference between both are: Primary transducer:The Mechanical device which converts physical quantity to be measured into a mechanical signal. Secondary tranducer:The Electrical device which converts this mechanical signal to the electrical signal.
What is mean by signal?
Signal is the electrical(discussion is confined to electrical domain only) quantity which varies between two levels and holds some useful information.
Do Fiber-optic cable send or receive electrical signal?
No. Fibre optic cables use light instead of electrical signals. Depending on the function of the optical fibre either a laser or an LED will be used.
What is optical communication?
An optical fiber is a flexible, transparent fiber made of very pure glass (silica) not much bigger than a human hair that acts as a waveguide, or "light pipe", to transmit light between the two ends of the fiber. The field of applied science and engineering concerned with the design and application of optical fibers is known as fiber optics. Optical fibers are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communication. Fibers are used instead of metal wires because signals travel along them with less loss and are also immune to electromagnetic interference. Fibers are also used for illumination, and are wrapped in bundles so they can be used to carry images, thus allowing viewing in tight spaces. Specially designed fibers are used for a variety of other applications, including sensors and fiber lasers.
What is the example of primary and secondary tranducer?
the difference between both are: Primary transducer:The Mechanical device which converts physical quantity to be measured into a mechanical signal. Secondary tranducer:The Electrical device which converts this mechanical signal to the electrical signal.
What carries information in the form of electrical sighals?
Signal curcuits are used for many different purposes. Wires carry electrical signals.
There is no liquid in LCD so why you call him LCD?
Liquid crystal displays use crystals that are not solid. The optical transparency of the crystal is adjusted with an electrical signal. The crystal will change its orientation as the signal is varied. It is this fluid motion that classifies the crystal as a liquid.
