Advantages of a Tuned Radio Frequency (TRF) receiver include simplicity in design, lower cost compared to superheterodyne receivers, and high selectivity for tuning in to specific radio frequencies. Additionally, TRF receivers can be easily modified and customized for specific applications or requirements.
can a superheterodyne receiver generated high noise
Those AM receivers that are built in superheterodyne configuration almost always have 455 KHz as their IF frequency. I've known this now for about 60 years, but still have no idea where that number came from. It seems an unwise choice, since, for roughly the lower half of the AM band, it places the local oscillator necessarily smack in the upper half of the band. But I'm sure that several engineers smarter than I had good reasons for putting it there.
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.
