Trasmitting stations have their own transmitting frequency.
No one can construct an amplifier which amplifies signals over a wide range.
So every transmitting frequency has to be changed to one particular frequency. This is known as INTERMEDIATE frequency (IF)
This is quite possible by getting beats.
So a signal is to generated whose frequency is just more than the incoming frequency by IF
This signal is named as local singnal which is generated by the LOCAL oscillator.

Differetiate between LC oscillators and crystal controlled oscillators?
LC oscillators use inductors and capacitors to generate a frequency, while crystal controlled oscillators use a quartz crystal to establish the frequency. LC oscillators can be less stable and accurate compared to crystal controlled oscillators, which offer better precision and stability. Crystal controlled oscillators are commonly used in applications where precise frequency control is essential.
What is use of inverting amplifier?
To create oscillators...........
State four types of LC oscillators?
Four types of LC oscillators include voltage controlled oscillators, drift control oscillators, crystal oscillators, and tuned circuit oscillators. A tuned circuit oscillator is the most common type of oscillator.
What products use the capacitor?
The products that uses the capacitor are filters and oscillators.
Why LC oscillators are not used for low frequency?
They are not suitable for use as extremely low-frequency oscillators because the inductors and capacitors would be large in size, heavy, and costly to manufacture.
Why RC oscillators are not suitable for high frequency generation?
Because an RC oscillator is affected by stray capacitance in the active components in the circuit. HF oscillators use an LC tuned circuit to define the frequency.
Closed loop gain for feedback oscillators?
Feedback oscillators have a closed loop gain of
