Question 2.Question :(TCO 4) From the spectrum analyzer display below, determine the modulation frequency. Student Answer:5KHz15KHz30KHz90KHz
200KHzInstructor Explanation:Modulation frequency is the difference between any two consecutive frequencies. The center frequency is 200 KHz. Each division is equal to 160/4 = 40 KHz. The next frequency is about 110 KHz. Modulation frequency = 215 – 200 = 15 KHz.
