Question

Thanks! The AM broadcast band occupies approximately 500 to 1600 kHz. The most well known AM receivers are using the superheterodyne technique, which enables important signal processing operations, such as demodulation, to be done at a more convenient lower frequency, rather than at the original high frequency of the incoming signal. Assume now that an AM superheterodyne receiver uses an Intermediate Frequency (IF) of 455 kHz. It is tuned to a specific station, and the frequency of the Local Oscillator (LO) is set to 1365 kHz. At what frequency is the station broadcasting? An AM receiver uses an IF frequency of 455 kHz. A radio station at 1200 kHz modulates its carrier with a maximum audio frequency of 9 kHz. What are the highest and lowest frequency components that the station is broadcasting? What are the highest and lowest frequencies that must be passed without much loss by the receiver's IF amplifier in order to recover the original audio signal?
