A station started broadcasting on the commercial AM system with the frequency 620 kHz, while a second station is broadcasting at 660 kHz. Knowing that the first station is transmitting the signal m, shown below while the second station is broadcasting the signal m, if the receiver uses high-side tuning with IF - 455 kHz, and an RF filter with 140 kHz bandwidth: i Calculate the image frequeney of each station ii. Propose IF filter characteristies (center frequeney and bandwidth) to ensure no interference. ii. When listening to the first station, draw the spectrum in three locations: before the IF filter, after the IF filter, and before the audio amplifier.
