What is the disadvantageand advantage of Superheterodyne receiver?
can a superheterodyne receiver generated high noise
What is the importance of Intermediate Frequency stage of the superheterodyne receiver?
for better output,and low impedance.!@
Why TRF receiver was replaced by superheterodyne?
Superheterodyne is:more sensitive than TRFmore selective than TRFeasier to tune than TRFeliminates the squeal that sometimes happens with TRFis easier to adapt to FM and TV reception than TRFcan be adapted for use with microwave signals to up/down convertetc.
What are oscillators used for?
Signal generators: reference (tuning equipment) source - such as electronic keyboards beat frequencies - as in a superheterodyne radio
What are the 4 parts to a receiver?
radio frequency amplifier intermediate frequency( If strip) in a superheterodyne radio mixer /demodulator Audio amplifier
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 has the author Carroll W Rowland written?
Carroll W Rowland has written: 'Excess noise in tunable diode lasers' -- subject(s): Superheterodyne receivers, Lasers
What is an example of an electronic device that does not have an operating system?
a "5 tube AC/DC superheterodyne radio", also called "The All-American Radio"pocket transistor radiocassette tape recorderwire recordercrystal radioetc.
Why intermediate frequency transformers are used in modulation process?
They are used as adjustable bandpass filters in superheterodyne (Google it) recievers. They determine how well you can select the radio station you require, while rejecting those close to it. They work in a fixed frequency range where their characteristics can be optimised.Very many modern radio recievers use some form of the superheterodyne principle though the function of the IF Transformer (ie bandpass filter) can be realised digitally, as in mobile phones for example. For AM radio a bandwidth of 9 KHz at 450KHz is typical.
What is Double conversion receiver?
A type of superheterodyne radio using two separate mixers, each producing its own intermediate frequency. The block diagram of such a receiver is like this: RF -> M1 -> IF1 -> M2 -> IF2 -> D -> AF

What is the standard if value for am receivers is?
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.
