Question

02. If you have a number of radio stations send their own programs at different carrier frequencies, all simultaneously. For instance, a radio receiver is tuned to receive AM modulated wave sent at carrier frequency of frR 980 kHz. the receiver LO is set at fio- 1435 kHz. For the given data: 1. Calculate frequencies at the receiver's mixer output. 2. Which frequency should be chosen as the intermediate frequency (IF)? 3. At what frequency the image radio station would operate? 4. Plot frequency domain graph of the frequencies produced in this question. 5. Plot frequency domain graph of the 2d, 3d, and 4th harmonics and intermodulation products.
