What are the types of signal?
An Analog Signal is a continuous signal, just like an electric current that flows through the copper cables when your electrical appliances are turned on. This continuous signal represents physical measurements. An example of this would be with an analog audio signal, the voltage amount of the signal changes continuously with the change in sound waves. Analog Signals are normally represented as electrical signals, but there is also Classical Mechanics, Pneumatics, and Hydraulics technique's that can be used in analog signals.
How are analog signals transmitted-?
Analog signals are transmitted as electrical waves.
What is the difference between transistor and transformer?
A transistor in the right circuit, contributes a POWER GAIN by taking energy from an external power supply. A transformer actually has losses but is primarily used for Impedance Matching. This is very useful in establishing the most efficient arrangements for transmitting power from the source to the load. Impedance matching is an important function of all power transfer systems.
What wave type is used by digital communications?
In digital communications, a digit is either a one or a zero, or an "on" or an "off" signal. The wave shape that is composed of "on's and off's" is the square wave.
What is a triangle-wave voltage function?
Triangle-wave voltage signal is a periodic signal that always has a constant positive and negative slope and no zero slope. It is exactly how it is sounds... a triangle shaped wave. /\/\/\/\/\/\/\/\/\/ - just like that. Nothing in this world can naturally produce perfect triangle waves. Every vibrates as periodic sinusoid. Triangle waves can be generated from sin waves with the use of Fourier Series. http://en.wikipedia.org/wiki/Fourier_series By summing sin waves with different periods nearly any time-continuous signal can be created. -VM
What part of a microphone converts sound waves into an electrical signal?
The diaphragm
What are the devices which converts sound signal into electrical signal other than microphone?
One is the hydrophone, used to pick up sound waves underwater.
What does a microphone and speaker have in common?
They both convert between electrical impulses and sound waves. The microphone converts sound waves into electrical impulses and the loudspeaker converts electrical impulses into sound waves.
What piece of station equipment converts electrical signals to sound waves?
a speaker's 'coil' (and magnet) converts electrical signals to sound
For radio broadcasts sound signals are converted to?
For radio broadcasting, sound waves are converted to electrical waves that are further transmitted. This transformation is done by a device called a transducer, which converts physical parameters into an electrical form (signals).
What type of device converts an electrical signal into electromagnetic waves for transmission through a channel?
transmitter
What is microphone and its functions?
A microphone is a device that picks up sound waves, converts the waves in to electrical pulses to be sent down cables or by wifi. A speaker receives the electrical pulses and converts the pulses back in to sound waves that a person can hear and understand.
Is it possible to convert sound waves to electrical energy?
we can convert sound waves to electric waves and by giving supply we can generate sounds to Piezo electric crystals or ceramics. The process of converting sound waves to electric waves with the help of peizo electric crystals is called peizo electric effect
A device that converts sound waves into an electronic signal that is transmitted through wires is a?
It is a microphone or a telephone.
What device converts sound waves to electric current?
Microphones will convert sound waves into electrical signals. An ear (i..e human ear) will also convert sound waves into electrical signals.
What is the use of the speaker?
A speaker converts the energy of discrete electrical impulses to the energy of sound waves in the air.
How does microphones change sound energy to electrical energy?
Teh varying pressure of the air (the sound) causes a varying electric potential in microphones. There are various techniques, one is called "dynamic microphone" whereby a membrane with a coil is allowed to move inside a magnetic field. The sound moves the membrane, the movement of the coil inside the magnetic field generates a current in the wire which is the signal. Ten kinds of microphone are discussed on Wikipedia (see Related link below)
