Want this question answered?
because noise usually changes the amplitude not frequency.
Yes the transformer effects the incoming frequency supply. This frequency is dependent on the core lamination of the transformer the weightier the core lamination the lesser will be the frequency we get and vice verse..
SHOT Noise
a transformer or inductor or capacitor does not change frequency frequency is controlled at the generating station with the speed of the motor or turbine the number of phases will not make a difference an inductor or capacitor can shift phase up to 90 degrees you can make 3 phase power from single phase power with inductors capacitors and transformers
Transformer capacity (kvA) shall be identical, Both transformer impedance, secondary voltage and frequency shall be identical.
In transformer there is no rotating part.so frequency constant.
noise are assumed frequency independent......
First we know that transformer is a statical electrical device that transfer electrical energy from one circuit to another circuit with out change its frequency .....it may be voltage or current is change simultaneosuly or separately .... and point is why does not change the frequency in the transformer because the there is no moving part in transformer....As we know that frequency is depends upon the rotation....
In general, the lower the frequency of operation, the more weight must be added to the core laminations to avoid magnetic field saturation. This increases the size and weight of the transformer as the frequency decreases.
The basic function of a transformer is to change voltage levels.

intermediate frequency transformer (ift) acts as a band selective n/w. the ift which is 455 khz is then given to IF amplifiers which is then given to detector.
we cannot use transformer because transformer cannot change frequency . . .
