What is the purpose of the local oscillator in a superhetrodyne receiver?

• To generate an intermediate frequency signal

• To filter out unwanted frequencies

• To demodulate the received signal

• To amplify the received signal

What is the intermediate frequency (IF) in a superhetrodyne receiver?

• Intermediate frequency (IF) is the frequency at which the incoming radio frequency (RF) signal is mixed with a local oscillator (LO) signal to produce a lower frequency signal that is easier to process.

• Intermediate frequency (IF) is the frequency at which the incoming radio frequency (RF) signal is amplified.

• Intermediate frequency (IF) is the frequency at which the incoming radio frequency (RF) signal is demodulated.

• Intermediate frequency (IF) is the frequency at which the incoming radio frequency (RF) signal is transmitted.
