What is the difference between audio generator and signal generator?
Audio generator will produce some range of frequency and level of a test signal meant for audio. A signal generator will produce a test signal but is a more general classification. For example a audio generator is a signal generator. When you know what type of signal you are looking for, then a signal generator will be called that type of signal. all depends on what you are testing. examples: video -> video signal generator audio -> audio signal generator
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 .
Is audio signal an electromagnetic signal?
Because Audio waves move as sound waves through air as condensations and rarefactions or slight compressions and partial vacuums of gas molecules and can be stopped by the walls of a house.
How do you convert voice signal to voltage?
different method are available for converting voice signal to volage ......one method is sence presure variation from the out put of mic by using presure tranducer ..out of transducer should be a volage .this volage is amplified by using amplifier cicuit and it amplified signal or volge is store in to battery or other storig device.......
What Distortion or unwanted noise in audio signal?
Noises present in audio signal may be of various kinds like environmental noises, transmission noises etc.
How magnet is used in telephone?
Magnets are used in the listening device, better known as the ear peice. It would convert electrical energy to mechanical energy. The ear peice would move with the fluctuations of the audio electrical signal, thereby moving a membrane to oscillate at the audio frequency of the electrical signal. Also, in very old telephones they would use the magnets as an electrical generator when you rotated the handle to produce an AC signal that would ring a bell on the Operator's end of the line. This would signal the Operator that you wanted to make a call by "ringing her bell".
What is function of pressure transmitter?
a pressure transmitter is a devise to measure the mechanical pressure and convert in to electrical signal it may be 4~20mA or 0~10V
What is audio singnal?
An audio signal is a representation of sound, typically as an electrical voltage. Audio signals have frequencies in the audio frequency range of roughly 20 to 20,000 Hz (the limits of human hearing).
What purpose does a vga to HDMI serve?
VGA to HDMI cable convert an analogue signal to a digital signal. It does this by connecting an audio cable to the adapter, where the video signal is fused with the audio also, so there is only one cable connecting to your HDTV.
Audio Connectors?
Audio connectors and video connectors are electrical connectors for carrying audio signal and video signal, of either analog or digital format. Analog A/V connectors often use Shielded cable to inhibit radio frequency interference (RFI) and noise.
How does a radio signal go from a disc jockey speaking into a microphone at a radio station to your ear?
In the microphone, there is a diaphragm, which converts the DJ's voice into an electrical signal. This signal is sent along the wire to the antenna, which broadcasts it into the ether. Your home radio receives the signal through its aerial, then converts the signal from an electrical signal to audio - which is detected by your ear.
How do you convert s video to composite video?
You need a RF modulator to convert the signal to a (RF) TV channel. The audio and video quality will be lower doing this.

How do a transverse wave carry audio signal?
the audio signal is put on transverse wave .
This converter is for audio only, not for a TV signal.?
This converter is for audio only, not for a TV signal.
How electromagnets are used in speakers?
An electromagnet is used to convert electrical signal to speech signal. It is made up of a metal coil which produces magnetic field when current is passed.
What is the function of the microphone in telephone?
To convert the users voice into an electrical signal, so that it may be transmitted to the person they're in conversation with.
