Superheterodyne is:
- more sensitive than TRF
- more selective than TRF
- easier to tune than TRF
- eliminates the squeal that sometimes happens with TRF
- is easier to adapt to FM and TV reception than TRF
- can be adapted for use with microwave signals to up/down convert
- etc.

How does the NGT works?
NGT means Neutral Grounding Transformer. It is Connected between TRF star point and earth point. It is protect the trf from short ckt .
Why you use 455kHz frequency as an intermediate frequency in communication?
The intermediate frequency in the superheterodyne receiver is chosen as the desired compromise between sensitivity and selectivity. 455kHz is used in AM broadcast applications, while 10.7mHz is used for FM. The IF stage is tuned for a steep skirt passband at that frequency, allowing only the desired heterodyned (shifted) input signal to make it through to the demodulator.
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 broadcast receiver?
A broadcast receiver is a radio that receives broadcasts from commercial radio stations.
The receiver will be able to decode the message if the transmitter and receiver share the same?

Advantages of TRF receiver?
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.
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.!@
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 are the 4 parts to a receiver?
radio frequency amplifier intermediate frequency( If strip) in a superheterodyne radio mixer /demodulator Audio amplifier
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
