What is the frequency of a local oscillator in super heterodyne?

A superheterodyne receiver is to operate in the frequency range 550 kFz-1650 kHz, with intermediate frequency of 450 kHz.

What is local oscillator in superheterodyne receiver?

The local oscillator is the heart of the receiver. It is the most critical circuit in the entire receiver because any drift or instability in the local oscillator will translate into drift and instability in the received signal.

What is the local oscillator frequency?

In electronics, a local oscillator (LO) is an electronic oscillator used with a mixer to change the frequency of a signal. This frequency conversion process, also called heterodyning, produces the sum and difference frequencies from the frequency of the local oscillator and frequency of the input signal.

How do I choose a local oscillator frequency?

With an IF of 10.7 MHz the local oscillator (LO) can be 10.7MHz lower (or higher) than the signal to be received. For instance, if you wish to tune a radio station at 88 MHz then the LO will need to be 77.3 MHz (or 98.7MHz) and here's the subtlety....
