Transformers are devices that use the principle of coupled magnetic fields to step voltage up or down, or provide DC isolation in circuits. A signal transformer is a special application of a transformer that is used to couple a signal from one circuit into another circuit. The signal might be stepped up (or amplified), or it might be stepped down, or it might be coupled without an increase or decrease simply to provide isolation, impedance matching, or phase shifting from stage to stage in an electronic device.

What will happen when a single diode is connected to a transformer with ac signal?
it convert ac signal into dc signal But it will give only half-wave rectification.
What difference's between potential transformer and voltage transformer?
Both are same. This is an instrument transformer used for metering & protections.
What is the name of the transformer that reduces the voltage?
a step down transformer is used to lower the voltage from the powerlines into your home. a common slang term for this type of transformer is a pole pig.
Can you use a transformer to convert modified sine wave to pure sine wave?
we cannot use transformer because transformer cannot change frequency . . .
What is the definition of audio-frequency transformer?
An audio frequency transformer is a transformer designed to operate in the range of frequencies audible to the average human. This range is generally accepted to be from 20 Hz to 20,000 Hz. The usual purpose of an audio transformer is to match impedances between circuit sections. For example: between a microphone and the input of an amplifier, (input transformer), or between the output of an amplifier and the loud speaker. (output transformer).
What is a continuously changing electric signal?
Transformer
What are the out put signal of current transformer?
kittys a w____R and so are you :)
How do you test a current transformer using a digital signal processor?
You don't.
What will happen when a single diode is connected to a transformer with ac signal?
it convert ac signal into dc signal But it will give only half-wave rectification.
Operation of a transformer?
Transforming a signal without changing its frequency.(amplitude can be changed)
What is a function of a Buchholz relay?
A Buchholz relay is designed to detect a failing oil-filled power transformer. It will automatically disconnect the transformer and produce an alarm signal.
How a transformer is very useful in ac supply?
Transformer is the only device which is capable to stepup or stepdown an ac signal. That's why its used widely in ac supply.
What is a transformer-coupled class A amplifier?
A transformer-coupled class A amplifier is just what it says it is. You'll recall that a class A amp is one that has an output that varies through all 360 degrees of an input signal. As regards the manner in which the signal is coupled to or from the stage, a transformer is used, complete with the non-linearity that it will introduce because of the characteristics of the (untuned) inductive component.
What does transformer coupled mean?
It means a signal has no direct (galvanic) connection to the next circuit, rather, the signal is sent (coupled) only through the magnetic field in the transformer. This is used where unwanted DC current would flow, or where a ground loop would result if a direct connection was used.
What is a signal pulse transformer?
usually a small transformer ferrite rather than iron core for short pulses it is more for isolation than anything else trigger for scr or triac the previous question for a power pulse transformer these are in cars ignition transformers the newer cars generally have one on each cylinder the computer may feed may feed a signal pulse through the small transformer to isolate the computer from the big one. to an scr to discharge a capacitor thru the ignition transformer (cars use the terms condenser and coil)
What is transducer and how it may be used to measure displacement?
Transducer is a device which convert physical signal into electrical signal ( current/voltage/resistance). for linear measurement we can use LVDT (Linear Variable Displacement Transducer/ Linear Variable Differential Transformer). and for rotary measurement we can use RVDT (Rotary Variable Differential Transformer)
Who supplies class 2 transformers?
Supplies of class 2 transformers can be found on Foster Transformer, Amazon, eBay, Surveillent, B&H Photo-Video-Audio, Sears, Altex Electronics, and Signal Transformer.
