1. The input to a certain AM receiver consists of a 1500 kHz carrier and two side frequencies separated from the carrier by 20 kHz. Determine the frequency spectrum at the output of the mixer amplifier.
2. For the same conditions stated in Problem 19, determine the frequency spectrum at the output
of the IF amplifier.
