What is the function of intermediate frequency transformer?
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.
Intermediate frequency amplifier in a TV receiver?
Is this sentence supposed to be question? Any superheterodyne receiver will have an IF amplifier. It doesn't matter whether TV or radio.
What does IF mean in an FM circuit?
IF stands for Intermediate Frequency. An intermediate frequency is a frequency which the primary signal or carrier signal signal is changed to in the process of reception or transmission. For example, an FM or frequency modulated radio or FM television tuner uses an intermediate frequency or IF of 10.7 megaHertz, abbreviated mHz. The primary signal of an FM radio may be between 88 to 108 mHz. This signal is processed to 10.7 mHz and then demodulated to an audio signal that human ears can hear. The reason for using an intermediate frequency is that it will not interfere with the primary or carrier frequency. Also, the lower IF frequency is easier to deal with electronically. Commonly used IF frequencies in FM are 10.7 and 5.5 mHz.AM or amplitude modulation commonly uses 455 kiloHertz although others frequencies may be used.
What is the advantages of using intermadiate frequency for satellite system?
There are three advantages to this type of frequency: 1) At very high frequencies (gigahertz), signal processing circuitry performs poorly. So a high frequency signal is converted to a lower intermediate frequency for processing. 2) In receivers that can be tuned to different stations, intermediate frequencies are used to convert the various different frequencies of the stations to a common frequency for processing. Without using intermediate frequencies, all the complicated filters and detectors in a radio or television would have to be tuned in unison each time the station was changed. 3) The primary advantage is that it improves frequency selectivity. In communication circuits, a very common task is to separate out or extract signals or components of a signal that are close together in frequency. This is called filtering. So a narrower bandwidth and more selectivity can be achieved by converting the signal to a lower intermediate frequency and performing the filtering at that frequency. Hope this helps!

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.

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.
