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.

Why frequency remains constant in transformer?
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....
What is intermediate frequency?
In communications and electronic engineering, an intermediate frequency (IF) is a frequency to which a carrier frequency is shifted as an intermediate step in transmission or reception. [1] The intermediate frequency is created by mixing the carrier signal with a local oscillator signal in a process calledheterodyning, resulting in a signal at the difference or beat frequency. Intermediate frequencies are used in superheterodyne radio receivers, in which an incoming signal is shifted to an IF for amplification before final detection is done. The intermediate frequency stays the same for all signals, for example 455 kHz in an AM broadcast receiver.Conversion to an intermediate frequency is useful for several reasons. When several stages of filters are used, they can all be set to a fixed frequency, which makes them easier to build and to tune. Lower frequency transistors generally have higher gains so fewer stages are required. It's easier to make sharply selective filters at lower fixed frequencies.

What is intermediate transformer?
I suspect you mean an "Intermediate Frequency transformer", or IF transformer. Superheterodyne (Or superhet) receivers convert the frequency of an incoming signal to a special frequency called the "Intermediate Frequency" or "IF". Most of the amplification takes place in the IF Amplifier which usually has several stages. Each of these stages is coupled to the next stage by a tuned transformer called an IF transformer. For AM receivers, the Intermediate frequency is usually 455 KHz, and for FM receivers it is usually 10.7 MHz. These transformers are usually about 20 turns of Litz wire on a plastic former with a dust-iron adjustable core. It sits in a little metal shield can.
Are intermediate frequency transformers are step up transformers?
Intermediate frequency transformers can be either step-up, step-down, or 1:1. The term "intermediate frequency" relates to the frequency of operation, and not to the voltage or current conversion ratios. An "intermediate frequency transformer" is a special purpose transformer used for filtration purposes in radio reception, rather than voltage or current conversion, though a step-up or step down turns-ratio may be used in the design.
Why is intermediate frequency transformer used in amplitude modulation?
used as a adjustable band pass filter...
