A transmitter transmits an AM signal with a carrier frequency of 1470 kHz. When a superheterodyne radio receiver (which has a poor selectivity in its RF-stage bandpass filter) is tuned to 1530 kHz, the signal is heard loud and clear. However, if this radio is cheap, its front-end bandpass filter is not very selective. Thus, the same signal is also heard (not as strongly) when tuned to another carrier frequency setting within the AM range of 535-1605 kHz. State, with reasons, at what frequency you will hear this station. The IF is 455 kHz.
